Mimba inotanga panguva yekusangana, kureva kusangana kweoocyte nembeu. Kana yangopinda muoocyte, nucleus yesperm inowedzera muhukuru, sezvinoita nucleus ye oocyte. Izvo zviviri zvinouya pamwechete uye pakupedzisira zvinobatana: nokudaro kuberekwa zygote, sero rekutanga pamavambo ehupenyu hwose. Iri zai rinotakura zvinhu zvese zvema genetic zvinodiwa pakuvaka munhu.

Inenge maawa makumi matatu mushure mekusangana kunotanga segmentation: zygote inoparadzanisa kakawanda, ichienda kune uterine cavity. Mazuva mapfumbamwe mushure mekusangana kunoitika kuisirwa: zai rinoiswa muchibereko chechibereko.

Pavhiki yechitatu yekuzvitakura, zai rava embryo, mwoyo wake unotanga kurova. Inobva yayera 3 mm uye masero ayo anoramba achipatsanura uye otanga kusiyanisa maererano nenhengo.

Pakupera kweizvi mwedzi wokutanga pamuviri, mwedzi 1 embryo zviyero zvinenge 5 mm. Iine "musoro" uye "muswe" wakasiyana, mabhudzi emaoko ayo, nzeve yemukati, ziso, rurimi. Organogenesis yatanga uye kutenderera kwe "fetus-maternal" kuri panzvimbo. Kubata pamuviri kunoonekwa pa ultrasound pamwedzi 1 uye kurova kwemoyo kunoonekwa (1) (2).

Sezvo hupenyu hunovamba mumuviri wavo, amai vanohufuratira nguva yose Mwedzi wekutanga wemimba. Izvo chete nekunonoka kwekuenda kumwedzi pamasvondo e4 kuti pamuviri unofungidzirwa. Mwana ane mwedzi 1 ekuberekwa, iyo ichava fetus, yatova nemavhiki maviri ehupenyu.

Nekukurumidza, zvisinei, muviri waamai uchaita shanduko dzakasimba pasi pekuita kwemahomoni ekuzvitakura: iyo hCG inovanzwa ne trophoblast (yekunze layer yezai) iyo inozoita kuti corpus luteum irambe ichishanda. (kubva kufollicle) iyo inobudisa progesterone, inokosha pakusimwa kwakakodzera kwezai.

Iyi hormonal mamiriro ekunze anogona kutotungamirira kune zvakasiyana zviratidzo zvepamuviri mumwedzi wekutanga :

• Nausea
• kunzwa kunhuhwirira
• chipfuva chakazvimba uye chakasimba
• kumwe kushatirwa
• hope masikati
• kazhinji kuda kuita weti

Chibereko chiri kukura: ukuru hwewalnut kunze kwepamuviri, iko zvino hukuru hweclementine. Uku kuwedzera kwevhoriyamu kunogona kutungamirira kune tightness, kunyange kurwadziwa mudumbu rezasi mukati memwedzi wekutanga wekuzvitakura. 

Dumbu remukadzi ane pamuviri ane mwedzi 1 haisati yaonekwa, asi ichawana vhoriyamu mwedzi nemwedzi panguva yese yekuzvitakura.

• Tora bvunzo yekuzvitakura mushure memazuva mashoma ekunonoka nguva
• kana ongororo iri positive, itai kuonana nachiremba wemadzimai kana nyamukuta. Ongororo yekutanga yekumanikidzirwa yeprenatal (3) inofanira kuitika isati yapera 1st trimester asi zvinokurudzirwa kubvunza zvisati zvaitika.
• ramba uchiwedzera vhitamini B9 kana yakatemwa panguva yekushanya kwekutanga

• 1 mwedzi nepamuviri, muchiitiko chekubuda ropa, kurwadziwa kwakanyanya mudumbu rezasi kana kune rumwe rutivi, zvakakosha kubvunzana kuitira kuti ubvise chero kusafungira kwekuparara kwepamuviri kana ectopic pregnancy.
• kana izvi zvisati zvaitwa panguva yekuongorora-pre-conceptual assessment, zvinokurudzirwa kuita chirongwa chemuromo kuitira kuti udzivise chero matambudziko panguva yekuzvitakura.
• Kunyange kana pamuviri usingazivikanwi pakutanga, sekudzivirira, maitiro ane ngozi anofanira kudziviswa: kunwa doro, zvinodhaka, fodya, kutarisana ne-X-rays, kutora mishonga. Izvi zvinonyanya kukosha kuti padanho re organogenesis, embryo inonzwa zvakanyanya kune teratogenic agents (zvinhu zvinogona kukonzera kukanganisa).

Izvi zvinodaro nekuti kunwa doro panguva yekuzvitakura kunogona kutungamirira kune fetal alcohol syndrome inogona kukanganisa kukura kwe embryo ine mwedzi 1. Iyi syndrome inotungamira kune malformations, kukanganiswa kwekukura padanho retsinga uye kunonoka kukura. Mwana anowanzo zvarwa nguva isati yakwana. Fodya yakaipa kumunhu wese uye zvakatonyanya kune iyo mukadzi ane nhumbu even 1 month uye fetus. Usati wabata pamuviri, kusvuta kunoderedza kubereka. Mumwedzi wekutanga wepamuviri, kusvuta kunowedzera njodzi yekubvisa pamuviri uye kuberekwa nguva isati yakwana. Mukuwedzera, fodya inofanira kurambidzwa mukati memwedzi iyi ye9, asi kunyanya kune fetus ine mwedzi 1. Inokanganisa kunaka kwayo mu-utero kukura. Mwana weramangwana anogona kuzvarwa aine hurema. Mukuwedzera, kusvuta panguva yekuzvitakura kunowedzera dambudziko rekufema mucheche mushure mokuberekwa. 

Nezvekutora mishonga panguva iyi Mwedzi wekutanga wemimba, inofanira kuitwa chete pamazano ekurapa. Vakadzi vane pamuviri havafanire kuzvirapa. Mishonga yakasikwa uye yakachengeteka iripo yekubvisa zvirwere zvepamuviri. Mishonga yakawanda ine zvisingadiwe mhedzisiro uye mhedzisiro yekuvandudzwa kwe embryo ine mwedzi 1, nokuti harina simba rokuvabvisa. Zvakakosha kuve nechokwadi chekuti unotora mushonga, kunyanya kana uine pamuviri.
