Musadandaule, sizili zovuta kudziwa nthawiyo, ndikwanira kumvetsa kuti thupi la mkazi liri ndi chiyero chake, momwe ziwalo monga mazira ndi chiberekero zimagwira ntchito. Kunja ndondomekoyi imawoneka ngati mwezi uliwonse. Mwezi wakhala ukudziŵika ndi chikhalidwe chachikazi, chimodzi mwa zifukwa zomwe izi ndizozungulira, mwachitsanzo, nthawi kuyambira pachiyambi mpaka kumapeto kwa mwezi uliwonse ndi masiku 28 ndipo ndi ofanana ndi kutalika kwa mwezi.
Zakale, tsiku la kubadwa likuwerengedwera kuyambira tsiku loyamba la kumapeto kwake: Masiku 280 akuwonjezeka ku nambala iyi, yomwe ndi miyezi khumi yokha. Izi zinachitika chifukwa mmasiku akale panalibe chidziwitso chokwanira cha anatomy kudziwa tsiku la ovulation. Pofuna kuchepetsa masamu, mukhoza kuwonjezera 7 mpaka tsiku (chifukwa umuna umatha masiku asanu ndi awiri ndi asanu ndi atatu mphambu zisanu ndi zitatu (7-14) pambuyo pake, komanso kuchokera mwezi womwe watengedwa 3 (chifukwa chakuti mimba imatenga miyezi isanu ndi iwiri). Tiyerekeze kuti kumapeto kwa msambo kunachitika pa December 3, 2006 (03.12.2006), ndiye kuti kubadwa kwa mwana kuyenera kuchitika pa September 10, 2007 (10.09.2007). Ngati muli ndi nthawi yokhazikika yomwe imatenga masiku 28-30, ndiye kuti mutha kuwonjezera 14 m'malo mwa 7. Kapena yonjezerani masabata 40 musanafike kumapeto. Ndi masabata omwe asayansi akuganiza kuti ali ndi mimba. Ndipo masabata 40 pafupipafupi, mimba yabwino.
Amayi am'mbuyo samamvetsetsa njira iyi yowerengera, makamaka ngati akudziŵa nthawi yomwe chiberekero chimachitika. Zimakhulupirira kuti nthawi yoyenera kubereka ndi nthawi ya chiwindi (kutuluka kwa mazira ovary ndi kuyenda kwa chiberekero). Ndikumayenda kwa masiku 28, ovulation amapezeka tsiku la 14. Ndi panthawi ino kuti mwayi wa feteleza dzira ndi waukulu kwambiri. Spermatozoon imakhalabe yamoyo kwa masiku asanu ndi atatu, kutanthauza kuti mkazi akhoza kutenga mimba ngati kugonana kunachitika pa tsiku la 9 mutangoyamba kumene kusamba. Izi zikutanthauza kuti, masiku atatu pambuyo pa kugonana. Zosangalatsa? Koma zoona! Popeza ovum amakhala ndi tsiku limodzi lokha, atatha kuyamwa, kutenga mimba pambuyo pa nthawiyi sikungatheke.
Ngati kutuluka kwanu kuli kosiyana ndi muyezo, nthawi yowombera mimba ikhoza kuwerengedwa pogawira kutalika kwa kayendetsedwe kake ndi 2. Masiku okondweretsa mwana wanu - masiku 4 asanayambe kuvuta ndi tsiku la ovulation palokha, ndiyeno mwayi wa pakati umachepa kwambiri.
Palinso njira ina, pambali yeniyeni, momwe mungadziwire tsiku la ovulation. Izi zimachitika pozindikira kutentha kwapansi. Mwinamwake mkazi aliyense amadziwa za njira iyi. Miyeso iyenera kupangidwa tsiku ndi tsiku nthawi imodzi, simungathe kutuluka pabedi, ndipo nthawi yoyezera iyenera kukhala maminiti 10. Asanayambe kuvuta, kutentha kwapakati sikupitirira 37.0 ° C, ndipo pambuyo - kudutsa pafupifupi 0,2 ° C. Tsiku loyamba kutentha kukudumpha (patsiku lino kutentha kumachepa kwambiri), kungokhala tsiku la ovulation. Poyerekeza kutentha kwa basal kwa miyezi itatu yotsatizana, mukhoza kulongosola molondola zam'tsogolo.
Kwenikweni, tsiku la kubadwa limatsimikiziridwa ngati mukudziwa nthawi yobereka kapena ovulation. Pankhaniyi, m'pofunika kuwonjezera osati 280, koma masiku 266 - nthawi yeniyeni ya mimba. Ngati ulendo wanu umatha masiku 28, ndiye kuti pasakhale kusiyana kulikonse pakati pa kuwerengera kwa ovulation ndi mwezi uliwonse. Komabe, ngati kayendetsedwe kake kamakhala kosiyana, zosokonekera mu zotsatira ndizotheka. Izi zikutanthauza kuti ngati mkombero uli waufupi kusiyana ndi muyezo, ndiye kuti tsiku lenileni la kubadwa lidzakhalanso nthawi yowerengera mwezi uliwonse, ndipo ngati mkomberowo utali wautali, ndiye kuti, mosiyana, mofananamo.
Masiku ano, kuti mudziwe tsiku lopereka, ultrasound ingagwiritsidwe ntchito. Ulosiwu umadalira kukula kwa mimba, ndipo kulondola kwake kumadalira momwe oyambira ultrasound anali atayambira kale. Choncho, ngati phunziroli lichitidwa m'masabata 12 oyambirira a mimba, ndiye kuti tsiku lobadwa la mwanayo likhoza kudziwika kuti pasanathe masiku atatu, ndipo ngati ultrasound ikuchitika masabata 12 achiwiri, kulondola kwafupika kukhala masiku asanu ndi awiri. Izi zili choncho chifukwa chakuti m'mimba yoyamba, kukula kwa mwana kumasintha bwino molingana ndi ndondomekoyi, ndipo m'masabata 12 omaliza kusintha kwake kumakhala kosiyana, choncho ndizosatheka kuti ulosi ukhalepo pa iwo.
Palinso nthawi yakale, komanso nthawi yomweyo, njira yosadziwika bwino yodziwira nthawiyo. Chokhazikika chake chimakhala pozindikira nthawi yomwe mayi wamng'onoyo ankamveketsa mwanayo. Pali lingaliro lakuti ngati mimba ndi yoyamba, ndiye kuti mayiyo adzaiwona pa sabata la 20, ndipo ngati yachiwiri, ndiye pang'ono - pa sabata la 18. Mu moyo, chirichonse chimachokera mosiyana, ndipo kukula kwa cholakwika cha lingaliro chotero kumapita mpaka masabata anayi. Kumvetsetsa kwa amayi ndi ntchito ya mwanayo ndipadera.
Mulimonsemo, ziribe kanthu momwe mukuwerengera tsiku limene munabadwa, nthawi zambiri sichichitika nthawi yomwe mudawerengera. Kuchedwa kwa milungu itatu ndi kotheka. Ndi bwino kubwereza kamodzinso, chifukwa nthawi zambiri zolakwika muzowerengera zimayambitsa nkhawa. Koma tiyenera kukumbukira chinthu chimodzi chofunikira. Mimba yabwino imatha kukhala masabata 38 mpaka 40. Ndipo ziribe kanthu kuti mumakhulupirira bwanji, mwanayo akhoza kubadwa pamasabata 38, ndipo izi ndi masabata awiri kutsogolo kwa tsiku loyembekezeredwa. Komabe, ngakhale zilizonse zomwe timawerengera ndi kuziwerenga, mwana mmodzi yekha amadziwa kuti ali wokonzeka kubadwa. Choncho, ndikupempha ndikungoyembekezera ndikusangalala ndi dziko lokongola.
