Izinguquko Esikhathini Sokuya Esikhathini Ngesikhathi Sokukhulelwa

Umjikelezo wokuya esikhathini uyisiyingi sokuzala kowesifazane esilungiselela umzimba wowesifazane njalo ngenyanga ukuze ukwazi ukukhulelwa. Ukuyeka kokuya esikhathini, okuthiwa i-periodo menstrual ngesiSpanishi, kuyisigaba somjikelezo wokuya esikhathini lapho udonga lwangaphakathi lwesibeletho lukhucululwa futhi lubonakala ngokopha komgodla wesitho sangasese sowesifazane [1].

Ngesikhathi salo mjikelezo, owesifazane udlula ezinguqukweni eziningi ezahlukene zomzimba. Ngokuvamile uthatha phakathi kwezinsuku ezingama-21 kuya kwezingama-35, kanti umjikelezo ojwayelekile uba yizinsuku ezingama-28 [2]. Umjikelezo wokuya esikhathini wuhlukaniswe waba izigaba ezinkulu ezine: isigaba sokuya esikhathini, isigaba se-follicular, i-ovulation, nesigaba se-luteal.

Kulesi sihloko, sizoxoxa ngemininingwane ngezikhathi ezahlukene zomjikelezo wokuya esikhathini, izinguquko emjikelezweni wokuya esikhathini ngesikhathi sokukhulelwa futhi siphendule imibuzo efana nalena ethi, ngokujwayelekile ukuya esikhathini kwenzeka nini.

Izigaba Ezehlukene Zomjikelezo Wokuya Esikhathini

Umjikelezo ojwayelekile wokuya esikhathini uthatha izinsuku ezingama-28 kodwa umjikelezo wezinsuku ezingama-21 kuya kwezingama-35 uyenzeka [2]. Umjikelezo ophelele uqukethe izigaba ezinkulu ezine. Isigaba ngasinye lihilela izinguquko ezahlukene esibelethweni ukulungiselela umzimba ukukhulelwa noma ukuguqula lezo zinguquko uma ukukhulelwa kungenzeki.

Nansi imininingwane ngezigaba ezahlukene zomjikelezo wokuya esikhathini:

1. Isigaba Sokuya Esikhathini

Umjikelezo wokuya esikhathini uqala ngesigaba sokuya esikhathini. Lesi sigaba siqala ngosuku lokuqala lokuya kwakho esikhathini ukuya esikhathini — i-period yakho — kanye sihlala cishe izinsuku ezi-3 kuya kwezi-7, kuya ngomuntu ngamunye.

Ngesikhathi salesi sigaba, isibeletho sikhuculula ungqimba waso wangaphakathi, owaziwa ngokuthi i-endometrium, obakhiwe ngesikhathi somjikelezo odlule ukuze kusekelwe ukukhulelwa okungenzeka. Lesi sigaba sibhekwa ngokopha kokuya esikhathini noma i-menses, lapho igazi, umchamo webele namaseli esicubu kukhishwa ngomgodla wesitho sangasese sowesifazane [3]. Amahomoni okukhulelwa kowesifazane, okuyi-estrogen ne-progesterone, abe sezingeni eliphansi kakhulu kulesi sigaba.

Izimpawu Zesigaba Sokuya Esikhathini

Lesi sigaba somjikelezo wokuya esikhathini sibuhlungu njengoba isibeletho sicwecwa bese sikhipha ungqimba salo sangaphakathi. Ungase uzwe ukuqunjelwa, ukushintsha kwemizwa, ukukhathala, ukuvuvukala nokungakhululeki ngesikhathi sokuyeka kokuya esikhathini, okwaziwa nangokuthi i-periodo menstrual noma i-menstrual period.

2. Isigaba se-Follicular

Isigaba se-follicular siqala ngosuku lokuqala lokuya esikhathini bese siqhubeka kuze kube i-ovulation, ngokuvamile cishe ngosuku lwe-13 noma lwe-14 kumjikelezo wezinsuku ezingama-28. Khumbula ukuthi lesi sigaba sihlanganisana nesigaba sokuya esikhathini futhi asiqali lapho isigaba sokuya esikhathini siphela.

Ngesikhathi sesigaba se-follicular, isibindi se-pituitary ebuchosheni sikhulula i-follicle-stimulating hormone (FSH), ekhuthaza ama-ovary ukuthi akhiqize amafolikhini. Izibiko zibonisa ukuthi amafolikhini angu-11 kuya kwangu-20 aqala ukuvuthwa emjikelezweni ngamunye, kodwa elilodwa kuphela elikhulula iqanda [4]. Amafolikhini asele ayabola ngaphakathi kwama-ovary.

Amazinga e-estrogen aqala ukwenyuka ekugcineni kwalesi sigaba ukuze alungise isibeletho ukuba sibe nokwenzeka kokukhulelwa. I-estrogen ikhuthaza ukujiya kodonga lwesibeletho ngokwakha izicubu nemithambo yegazi.

Izimpawu Zesigaba se-Follicular

Ngesikhathi sesigaba se-follicular, abesifazane bangabona amandla enyuka kanye nokuba semoyeni omuhle. Lezi zinguquko zibangelwa ukwenyuka kwezinga le-estrogen, eliphinde lithuthukise ukugxila nengcono inhlalakahle jikelele.

3. Isigaba se-Ovulation

I-ovulation ivame ukwenzeka maphakathi nomjikelezo wokuya esikhathini, ngokuvamile ngosuku lwe-14 emjikelezweni wezinsuku ezingu-28. Lena yisigaba esifushane kakhulu futhi sithatha cishe amahora angu-24 kuphela.

Ngesikhathi sesigaba se-ovulation, izinga le-hormone ebizwa nge-luteinizing hormone (LH) liqala ukwenyuka ngokuzumayo, lokhu okubizwa ngokuthi ukwenyuka kwe-LH (LH surge) [5]. Lokhu kuqhuma kwe-LH kuvusa ukukhululwa kweqanda kusuka efolikhini elivuthiwe. Iqanda alihlali ema-ovary; kunalokho, liya esiteshini se-fallopian lapho isidoda silichumisa khona.

I-ovulation yisikhathi somjikelezo wokuya esikhathini lapho owesifazane enekhono elikhulu kakhulu lokukhulelwa. Amathuba akhe okukhulelwa aphezulu kakhulu uma ehlela ukulala kobulili ezinsukwini eziseduze ne-ovulation [6].

Izimpawu Zesigaba Sokuvuthwa Kweqanda (Ovulation)

Ukuqonda izimpawu zesigaba sokuvuthwa kweqanda kubalulekile ngoba kusiza ukulandelela i-ovulation. Ukulandelela i-ovulation kusiza abesifazane bathole izinsuku zabo ezikhulisa kakhulu amathuba okukhulelwa futhi bahlele ukulala kobulili ngaleyo misebenzi ukuze bandise amathuba okukhulelwa.

Izimpawu kulesi sigaba zifaka:

• I-Mittelschmerz — ubuhlungu obuthambile noma ukungakhululeki esiswini esingezansi
• Ukukhuphuka kwethangi lokushisa komzimba (basal body temperature).
• Izinguquko kumafinyila wesibeletho — iba sobala futhi ishube njengobulwelwe beqanda.
• Ukukhula kwesifiso socansi noma uthando locansi.

4. Isigaba se-Luteal

Isigaba se-luteal siqala emva kokuvuthwa kweqanda (ovulation) futhi siqhubeke kuze kuqale inkathi yokuzala elandelayo. Lesi sigaba sivame ukuthatha cishe izinsuku ezingu-14.

Ngemva kokukhishwa kweqanda ngesikhathi sokuvuthwa (ovulation), isikhwama esisale senza ushintsho sibe yi-corpus luteum ngesikhathi sesigaba se-luteal, esikhiqiza i-progesterone [7]. I-progesterone isekela ungqimba lwesibeletho futhi inikeza indawo efanele ukuze iqanda elichumile lizimbe.

Uma ukufakelwa kwamaqanda kwenzeka, umzimba uqala ukukhiqiza i-human chorionic gonadotropin (hCG), ihomoni esekela ukukhulelwa futhi ethumela isignali ku-corpus luteum ukuthi iqhubeke nokukhiqiza i-progesterone.

Kodwa-ke, uma ukufakelwa kwamaqanda kungenzeki nganoma yisiphi isizathu, i-corpus luteum iyachithakala. Lokhu kuholela ekwehleni kwamazinga e-progesterone ne-estrogen futhi kubangele ukuchithwa kolwelwesi lwesibeletho. Lesi sehlakalo sibonakalisa ukuqala kokuya esikhathini.

Izimpawu zesigaba se-luteal

Izimpawu ezivamile ngesikhathi sesigaba se-luteal zifaka ukudinwa, ubuhlungu bamawele, kanye nokubamba kancane esiswini. Abanye abesifazane baphinde babe nokushintsha kwemizwa nokucasuka, okuthiwa ngokuvamile yi-premenstrual syndrome noma i-PMS.

Izinguquko Emjikelezweni Wokuya Esikhathini Ngesikhathi Sokukhulelwa

Uma ukukhulelwa kwenzeka, umjikelezo wokuya esikhathini uyaphazamiseka, bese kwenzeka lezi zinguquko ezilandelayo ukusekela umbungu okhulayo:

1. Ukufakelwa Kwamaqanda Nokufakelwa Embunjini: Iqanda lifakelwa isidoda esiteshini le-fallopian. Iqanda elifakwe isidoda — i-zygote — lihamba liye esibelethweni bese lifakelwa olweleni lwesibeletho.
2. Izinguquko Zamahomoni: Ngemva kokufakelwa, umzimba uqala ukukhiqiza i-hCG, evimba ukwephuka kwe-corpus luteum [8]. Lokhu kuqinisekisa ukuthi ukukhiqizwa kwe-progesterone kuyaqhubeka nokusekela ukukhulelwa. Izinga le-estrogen ne-progesterone lihlala liphezulu ukusekela ulwelwesi lwesibeletho.
3. Akukho Kuya Esikhathini: Ulwelwesi lwesibeletho alukhishiwe uma ukufakelwa sekwenzekile, ngakho ukuya esikhathini akwenzeki ngesikhathi sokukhulelwa. Esikhundleni salokho, lolu lwelwesi luyaqhubeka nokondla umbungu okhulayo.

Ekuqaleni Izimpawu Zokukhulelwa

Abesifazane abazama ukukhulelwa bavame ukubuza ukuthi bangazi kanjani ukuthi sebephumelele ukukhulelwa noma yiziphi izimpawu umzimba owazivezayo zokukhulelwa. Ukwazi kusenesikhathi izimpawu nezimpawu zokuqala zokukhulelwa, njengokuphuthelwa kokuya esikhathini noma isifo sasekuseni, kungakusiza uqinisekise ukukhulelwa kusenesikhathi futhi ufune ukunakekelwa kokubelethiswa okufanele. Nazi ezinye izimpawu ezingakhomba ukukhulelwa, ongakuqinisekisa ngokuhlolwa kokukhulelwa:

• Ukuphuthelwa kokuya esikhathini
• Isicanucanu noma isifo sasekuseni
• Amabele abuhlungu noma avuvukele
• Ukudinwa nokuchama kaningi
• Ukuvuza kwegazi okuncane, kwesinye isikhathi okuthiwa ukopha kokufakelwa

Ungakuqinisekisa Kanjani Ukukhulelwa?

Uma uqala ukuba nezimpawu zokuqala zokukhulelwa kanye nokubambezeleka kokuya esikhathini, yilona sikhathi esifanele ongaya ngaso ekwenzeni izivivinyo zokuqinisekisa ukukhulelwa [9].

Indlela ejwayelekile futhi elula yokuhlola ukukhulelwa wukuthenga ikhithi yokuhlola ukukhulelwa. Lezi zikhithi ziza nawo wonke amadivayisi adingekayo ukuze kwenziwe ukuhlolwa nokuchazwa kwemiphumela.

Izinga lehomoni ye-hCG liqala ukwanda ngokushesha ngemva kokuthi iqanda elichumiswe lifakeke esibelethweni. Lezi zikhithi zokuhlola zisebenza ngokuthola izinga lale homoni emchameni. Uma wenza lezi zifundo ulandela imihlahlandlela enikezwe abakhiqizi, ungathola imiphumela enembile kuze kufike ku-99%.

Enye indlela yokuqinisekisa ukukhulelwa ukuvakashela udokotela. Udokotela uzohlola ukukhulelwa ngokuhlolwa kwegazi noma i-ultrasound futhi akuholele mayelana nempilo yakho yokukhulelwa.

Okubalulekile

Ukuzala kowesifazane namathuba okukhulelwa kuncike kakhulu ekulungeni komjikelezo wokuya esikhathini. Ukuqonda umjikelezo wokuya esikhathini kungase kudide abesifazane ekuqaleni, baze bazithole bebuzisisa imibuzo efana nokuthi ngokujwayelekile isikhathi siya nini noma yiziphi izinguquko ezenzeka emjikelezweni wokuya esikhathini ngemva kokukhulelwa.

Ngokwesilinganiso, umjikelezo wokuya esikhathini uthatha izinsuku ezingu-28 futhi unezigaba ezine ezivelele. I-periodo menstrual noma isikhathi sokuya esikhathini yisigaba sokuqala somjikelezo wokuya esikhathini, kulandele isigaba se-follicular, isigaba sokuvuthwa kweqanda, nesigaba se-luteal. Uma ukukhulelwa kwenzeka, umjikelezo wokuya esikhathini uyama kuze kube kubelethwe ingane. Ukuphuthelwa izikhathi zokuzuza esikhathini nezinye izimpawu kungakusiza ukubona ukukhulelwa kusenesikhathi ongakuqinisekisa ngosizo lwemihlolelo yokukhulelwa.
