Nthawi yogonana imayesedwa mu masabata, koma masabata angakhale okondweretsa (kutanthauza kuti anawerengedwa kuchokera kumimba) ndi obstetric (kutanthauza, kuyambira pa tsiku lomaliza mwezi uliwonse). Kuyeza nthawi yogonana mu masabata osokoneza bongo ndi chinthu chosavomerezeka komanso chofala, chifukwa ndizosatheka kudziŵa tsiku lomwe ali ndi pakati. Mwachitsanzo, sabata la amayi asanu ndi awiri lakumayi la mimba likhoza kulingana ndi masabata asanu kuchokera pakulera (ngati feteleza ya dzira idachitika patatha sabata 2-3), ndi masabata anayi kuchokera pa mimba (ngati mimba idachitika pafupi ndi kutha kwa ulendo).
Masabata asanu ndi awiri ndi amodzi mwa nthawi yovuta kwambiri ya mimba, chifukwa panthaŵiyi thupi lachikasu silingathe kuthana ndi ntchito zake zothandizira mimba ndipo limapereka ntchito ku placenta. Komabe, placenta si nthawi zonse yokonzekera udindo wotero, chifukwa cha zomwe zingachitike padera padera. Ngati mayi ali ndi sabata lakumulendo 7 lakumulera, zizindikiro za kutaya padera zisamangomuyang'anitsitsa, koma zimutengeni kuti aone dokotala mwamsanga. Zizindikiro zoterezi zingakhalepo:
- kulumikiza ululu m'mimba pamunsi;
- kuona.
Embryo mu masabata asanu ndi awiri
Kumapeto kwa masabata asanu ndi awiri (7) mwana akhoza kutchedwa kale mwana, chifukwa nthawi yamakono ya chitukukoyo imatengedwa kukhala yodzaza. Ngakhale kuti mwanayo alibe kachilombo koyambitsa matenda ndi ubongo, ubongo ukupanga kale. Apo ayi, ali ngati munthu, kunja ndi mkati. Mitsempha yomwe inalipo pamayambiriro oyambirira a chitukuko, pafupifupi inatha, koma mchira wawung'ono ulipobe. Zipatso zimayendetsa pang'ono, malo pomwe padzakhala khosi lake. Miyendo imakhala yooneka bwino, koma zala sizigawanika panobe. Nkhumba zimakula mofulumira kuposa miyendo.
Nkhope ya mwanayo imakongoletsedwa, pakamwa ndi pamphuno zimaoneka, nsagwada zimayamba kupanga. Pamapeto pa nthawi iyi ya mimba, adzalandira chilakolako cha kugonana, komwe kenako ziwalo zogonana zidzapanga. Tsopano sizosatheka kudziwa momwe mwanayo aliri, koma mu majini izi ndizokonzedweratu.
Masabata asanu ndi awiri a mimba (obstetric period) amatanthauza kuti mwanayo wamtali akhoza kukhala mamita 5 mpaka 13, ndipo kulemera kwake kungathe kufika ma gramu 8. Kumapeto kwa sabata lachisanu ndi chiwiri pakati pa chiberekero ndi placenta, kugawidwa kwa magazi kumapangidwira, ndiko kuti, magazi a mayi ndi mwanayo akugwirizanitsidwa. Izi ndi zofunika kuti mwana adye ndi kupuma. Mphepete mwa chigwachi imakhazikitsanso, zomwe zimaletsa poizoni ndi tizilombo toopsa kuti tifike kwa mwanayo.
HCG imafufuza sabata 7
Kufufuza kwa msinkhu wa chorionic gonadotropin (hCG) pa sabata lachisanu ndi chiwiri lopweteka kumapangitsa kudziwa ngati mwanayo akukula bwinobwino. Mu 6-7 masabata osakanikirana a mimba, mlingo wa homoni iyi ukhoza kusiyana pakati pa 2560 ndi 82,300 MIU / ml. Pa masabata asanu ndi awiri ndi asanu ndi awiri ndi asanu ndi awiri (7) a mimba yovuta, hCG iyenera kukhala pakati pa 23,100 ndi 151,000 mIU / mL. Kusiyana kumeneku pakati pa chigawo chapamwamba ndi chapansi pa nthawi iliyonse ndi chifukwa chakuti nthawi ya umuna wa dzira ndi cholumikizira ku chiberekero cha mmimba chingakhale chosiyana. Tiyenera kukumbukira kuti kupanga HCG kumayambira nthawi yomweyo.
Sabata 7 loperewera mimba: zowawa
Sabata lachisanu ndi chiwiri lotha kutenga mimba lidzakumbukiridwa ndi amayi akubwera ndi kufika kwa toxicosis, kugona, kutaya mtima. Ziwalo zonse ndi ndondomeko zimayambanso kukonzanso, iwo akhoza kukhala ndi nkhawa chifukwa cha mutu, nkhawa kapena, pang'onopang'ono, mafunde amatha kusintha.
Nthawi yovuta ya masabata asanu ndi awiri ndi nthawi yoti ayambe kuyesedwa koyambirira kwa ultrasound, yomwe mtima wa mwanayo ukhoza kukhazikitsidwa. Mungathe kupatsanso mayesero omwe amaikidwa kuti alembetse mimba.
