Ishadi le-BBT Lokukhulelwa Kwangoko Nokwehla Ngesikhathi Sokunanyezela (Implantation Dip): Indima Yalokhu Kwehla Nezinguquko Ezingxenyeni Zokushisa Komzimba

Kwabalandela imijikelezo yabo yokuya esikhathini befuna izimpawu zokuqala zokukhulelwa, izinga lokushisa lomzimba eliyisisekelo (BBT) linganikeza ukuqonda okubalulekile. Enye inkomba ethile, eyaziwa ngokuthi ishadi le-BBT lokukhulelwa kokuqala elinezinga lokwehla ngesikhathi sokufakelwa (implantation dip), ingavela kushadi le-BBT ekuqaleni kokukhulelwa, ikhombise ukuthi ukufakelwa sekuke kwenzeka. Kulesi sihloko, sichaza ukuthi kuyini lokhu kwehla ngesikhathi sokufakelwa, indlela i-BBT engakhombisa ngayo ukukhulelwa, nokuthi yiziphi izinguquko ezingalinganiselwa ekushiseni komzimba ngesikhathi sokuqala sokukhulelwa. Sizobuye sixoxe nezinye izimpawu ezihlobene nalokhu, njengokuphuma koketshezi olunsundu nokubaluleka kwalo ekuqaleni kokukhulelwa.

Izinga Lokushisa Lomzimba Eliyisisekelo Nokukhulelwa Kokuqala: Kusebenza Kanjani

Ukuqapha i-BBT kuhlanganisa ukukala izinga lokushisa lomzimba ekuseni kakhulu, ngokukhethekile ngaphambi kwanoma yiluphi uhlobo lomsebenzi womzimba. Ngesikhathi somjikelezo ojwayelekile wokuya esikhathini, izinga lokushisa lomzimba eliyisisekelo liyashintsha ngenxa yezinguquko zama-hormone, ikakhulukazi i-progesterone. Ngemva kokuvuthwa kwamaqanda (ovulation), amazinga e-progesterone ayakhuphuka, okubangela ukukhuphuka okuncane ekushiseni komzimba. Lelo zinga lokushisa eliphezulu lihlala lizinzile kuyo yonke i-luteal phase (isigaba esilandelayo ngemva kokuvuthwa kwamaqanda) kuze kufike isikhathi sokuya esikhathini, lapho ama-level e-progesterone ehla khona, bese kwehla futhi ne-BBT [1].

Ekukhulelweni kokuqala, nokho, i-progesterone ihlala iphezulu ukuze ixhase udonga lwesibeletho, ngakho-ke i-BBT ihlala iphezulu esikhundleni sokwehla. Ishadi le-BBT lokukhulelwa kokuqala livame ukukhombisa ukukhuphuka okuqhubekayo kwezinga lokushisa okuqhubeka kudlule ejwayelekile i-luteal phase.

Kuyini Ukwehla Kwezinga Lokushisa Ngesikhathi Sokufakelwa (Implantation Dip)?

Ukwehla ngesikhathi sokufakelwa kubhekisela ekwehleni okuncane kwezinga lokushisa lomzimba eliyisisekelo okungenzeka phakathi kwezinsuku ezingu-6–12 ngemva kokuvuthwa kwamaqanda, cishe ngesikhathi sokufakelwa kwe-embryo. Ngesikhathi sokufakelwa, iqanda elichumile linamathisela odongeni lwesibeletho, okubangela ushintsho lwama-hormone lwesikhashana olungaholela ekwehleni okuncane kwezinga lokushisa. Lokhu kwehla kuvame ukuthatha usuku olulodwa nje kuphela, kulandele ukubuyela ezingeni lokushisa eliphezulu.

Nakuba lokhu kwehla ngesikhathi sokufakelwa kuyinkomba ethokozisayo, akuveli kuzo zonke izimo zokukhulelwa. Ucwaningo luphakamisa ukuthi cishe 25–30% wabesifazane abakhulelwe abahlangabezana nalokhu kwehla, ngakho noma kuwumuzwa omuhle ukubona lokhu kushadi le-BBT, ukungabi khona kwalo akusho ukuthi awukhulelwe. Kulabo abakubonayo, kubhekwa njengenkomba yokuqala engaba khona yokufakelwa okuyimpumelelo.

Ukuqapha Izinga Lokushisa Eliyisisekelo Ekukhulelweni Kokuqala

Ekukhulelweni kokuqala, izinga lokushisa lomzimba eliyisisekelo uma ukhulelwe lihlala liphezulu ngemva kokuvuthwa kwamaqanda. Ngokuvamile, izinga lokushisa ngemva kokuvuthwa kwamaqanda likhuphuka cishe ngo-0.4 kuya ku-1.0°F (noma ngo-0.2 kuya ku-0.5°C) ukusuka ezingeni eliyisisekelo futhi lihlala liphezulu ngesikhathi sokuqala sokukhulelwa. I-BBT ephezulu, ezinzile isikhathi esingaphezu kwezinsuku ezingu-16–18 ngemva kokuvuthwa kwamaqanda ivame ukuba inkomba eqinile yokuqala yokukhulelwa. Lokhu kungenxa yokuthi izinga lokushisa lomzimba ngesikhathi sokukhulelwa lihlala liphezulu ngenxa yokukhiqizwa kwe-progesterone yi-corpus luteum, kuthi kamuva lenze lokho isibeletho esisakhulayo (i-placenta) [2].

Kubalulekile nokwazi ukuthi ibanga elijwayelekile lezinga lokushisa ekukhulelweni kokuqala lingaba phakathi kuka-97.8–98.6°F (36.5–37°C). Nokho, izinga lokushisa lomzimba liyahluka kumuntu nomuntu, ngakho kuwusizo kakhulu ukubuka iphethini (trend) eshadini lakho kunokugxila kumazinga athile ezibalo.

Ukwehla Kwezinga Lokushisa Ekukhulelweni Kokuqala Nokushiwo Yikho

Uma uqaphela ukwehla okusheshayo kwezinga lokushisa, okubizwa kaningi ngokuthi ukuwa ngesikhathi sokufakelwa (implantation dip), kungase kube uphawu lokuthi ukufakelwa sekuqala ukwenzeka. Lokhu kwehla okuncane ekushiseni komzimba ekukhulelweni kokuqala kuvame ukwenzeka cishe phakathi kwezinsuku ezingu-7–10 ngemva kokuvuthwa kwamaqanda (DPO), kodwa njengoba kushiwo, akusona isiqinisekiso, ngoba akuvamile ukwenzeka kuzo zonke izimo zokukhulelwa. Lokhu kwehla ngokuvamile kuthatha usuku olulodwa, kulandele ukubuyela ebangeni lokushisa eliphezulu elivamile ekukhulelweni kokuqala [3].

Ezinye Izimpawu Ezihambisana Nokufakelwa

Ngaphandle kwezinguquko ku-BBT, abanye besifazane babika ukuphuma koketshezi olunsundu noma amabala egazi ngesikhathi esiseduze nokufakelwa. Lolu hlobo lwamabala, olwaziwa kwesinye isikhathi ngokuthi ukopha kokufakelwa (implantation bleeding), luvame ukuba lula futhi lube nesikhathi esifushane. Abaningi bayazibuza, “Ingabe uketshezi olunsundu kuwukufakelwa?” futhi kwezinye izimo, impendulo ithi yebo. Nokho, lokhu akusiwona umthetho, ngoba ukukhulelwa okuningi kuyaqhubeka ngaphandle kwanoma yiluphi uphawu olubonakalayo lokopha kokufakelwa.

Uma amabala anensundu noma apinki okhanyayo evela kungakapheli sikhathi eside ngemva kokuqagela ukwehla kwezingalo lokushisa ngesikhathi sokufakelwa, kungase kube enye inkomba yokukhulelwa kokuqala. Lawa mabala ngokuvamile awafani nokugeleza kokuya esikhathini futhi angavela njengokopha kokuqala kokukhulelwa okubukeka njengegazi elinsundu lokuyeka ukuya esikhathini elisemathinini (pad), elikhanyayo futhi elingahlali isikhathi eside njengokugeleza kokuya esikhathini [4]. Kwezinye izimo, abesifazane bangase babe ne-ukopha kokufakelwa okwephuzile, okwenzeka eduze nesikhathi abebengalindele ngaso ukuya esikhathini futhi kungadidaniswa nokuya esikhathini okuvamile.

Ingabe Igazi Elinsundu Ngesikhathi Sokuya Esikhathini Linguphawu Lokukhulelwa?

Igazi elinsundu lingahlobana nokukhulelwa kwezinye izikhathi, ikakhulukazi uma livela phakathi nesikhathi sokufakelwa. Nokho, uketshezi olunsundu noma amabala egazi awusho nakanjani ukuthi ukhulelwe. Igazi elinsundu ngesikhathi sokuya esikhathini livela egazini elidala elishiya umzimba, ngakho lingavela nasekuqaleni noma ekugcineni komjikelezo wokuya esikhathini. Uma ubona igazi elibukeka njengegazi elinsundu lokuqala kokukhulelwa emathinini (early pregnancy brown period blood on pad) ngesikhathi osanda kuphuthelwa ngaso ukuya esikhathini, kungcono ukubheka lokhu njengenye yezimpawu ezingaba khona phakathi kwezinye, hhayi njengesimemezelo esiqinisekile.

Izinga Lokushisa Lomzimba Ekukhulelweni Kokuqala: Ukuqonda Amaphethini

Ekukhulelweni kokuqala, izinga lokushisa lomzimba ngokuvamile lihlala liphezulu ngenxa yamazinga e-progesterone aqhubekayo. Ukuqapha leli banga lezinga lokushisa kunganikeza ukuqonda kulabo abazama ukukhulelwa ngamabomu. Kodwa-ke, kubalulekile ukukhumbula ukuthi ukuhlolwa kokukhulelwa yikho okuyindlela ethembeke kakhulu yokuqinisekisa ukukhulelwa, ngoba i-BBT yodwa ayikwazi ukukugcina uqinisekile. Ngaphezu kwalokho, izinto ezifana nokugula, ukungaphumuli kahle, noma izimo zemvelo zingathinta imiphumela yokukala izinga lokushisa.

Imibuzo Evame Ukubuzwa: Imibuzo Ejwayelekile Ngokukhulelwa Kokuqala, i-BBT Nokufakelwa

Kuthiwani uma ngingaboni ukwehla ngesikhathi sokufakelwa?

Ukungaboni ukwehla ngesikhathi sokufakelwa eshadini lakho le-BBT akusho ukuthi awukhulelwe. Abesifazane abaningi baba nokukhulelwa okuyimpumelelo ngaphandle kokuhlangabezana nalokhu kwehla, ngoba kwenzeka kuphela emaphesenti ambalwa ezimo.

Izinga lokushisa lami kufanele lihlale isikhathi esingakanani liphezulu uma ngikhulelwe?

Emjikelezweni ongakhulelwe, i-BBT ngokuvamile iyehla ngaphambi kancane noma ngesikhathi sokuqala sokuya esikhathini. Uma ukhulelwe, nokho, i-BBT ihlala iphezulu idlule isikhathi obulindele ukuqala ngaso ukuya esikhathini futhi iqhubeke kuze kube sekupheleni kwekota yokuqala yokukhulelwa.

Ngingakwazi yini ukuthembela ku-BBT yodwa ukuqinisekisa ukukhulelwa?

Ukuqapha i-BBT kungakunikeza izinkomba zokuqala, kodwa akufanele kuthathe indawo yokuhlolwa kokukhulelwa. Ukuqinisekiswa okuthembeke kakhulu kuvela ekuhlolweni kokukhulelwa ekhaya noma ekuhlolweni kwegazi elalelwa udokotela noma umhlinzeki wezempilo.

Ingabe ukwehla ngesikhathi sokufakelwa kubalulekile ukuze umuntu akhulelwe?

Cha, ukwehla ngesikhathi sokufakelwa akubalulekile. Kuwuphethini othokozisayo ongabonwa eshadini, kodwa ukungabi khona kwawo akukhuphuli noma kwehlise amathuba okukhulelwa.

Isifinyezo: Uyihumushela Kanjani Ishadi Lakho le-BBT Ukuthola Izinkomba Zokukhulelwa Kokuqala

Ishadi le-BBT lokukhulelwa kokuqala elinezinga lokwehla ngesikhathi sokufakelwa lingaba uphawu oluthembisayo uma libhekwa kanye nezinye izimpawu, kodwa akulona uphawu oluqinisekile. Ukukhuphuka okuqhubekayo kwe-BBT ngemva kokuvuthwa kwamaqanda, okuhlale kuphezulu kudlule ubude be-luteal phase ojwayelekile, kungakhombisa ukukhulelwa kokuqala. Uma ubona ukwehla kosuku olulodwa cishe phakathi kwezinsuku ezingu-7–10 ngemva kokuvuthwa kwamaqanda, kulandele izinga lokushisa elihlala liphezulu, lokhu kungase kukhombise ukufakelwa okuyimpumelelo.

Ukubuka ezinye izimpawu zokuqala ezifana nokuphuma koketshezi olunsundu noma amabala okopha angakhanyayo kungafaka umongo eshadini lakho le-BBT, nakuba lezi zimpawu zodwa zingaqinisekisi ukukhulelwa. Sekukonke, nakuba ukuqapha ukukhulelwa kokuqala nezinga lokushisa lomzimba nge-BBT kuyithuluzi elibalulekile kwabanye, ukuhlolwa kokukhulelwa ekhaya kusaluyindlela eqinisekisayo yokwazi ukuthi ukhulelwe yini. Abanye besifazane bakhetha ukusebenzisa imikhiqizo yokuzala esekela ibhalansi yama-hormone ukuze bandise amathuba abo okukhulelwa.

Ngokwazi ubuciko be-BBT kanye nemikhawulo yayo, ungasebenzisa le ndlela ukuze uthole ukuqonda ngomjikelezo wakho, ubone izimpawu zokuqala ezingaba khona zokukhulelwa, futhi uqonde kangcono izinguquko ezenzeka emzimbeni wakho.
