I-embryo evikini lesi-3 lokukhulelwa iqala ekuqaleni indlela yokuphila kwayo, yasinda emkhathini, ihlanganiswe ezindongeni zesisu futhi iqala ukuhlukaniswa okuyinhloko kwamaseli. Ukukhula kombungu emasontweni ama-3 wokubeletha, ngokusho kokubala kwe-obstetric, kungukuphela kwezinsuku eziyisikhombisa, kanti umama ozayo akakholelwa ngisho nokuba khona kwayo.
Isikhathi sokuphila se-embryo emavikini amathathu sibalwa ngezindlela ezahlukene futhi singalinganiswa namasonto ama-5 angama-obstetric noma izinsuku eziyisikhombisa kusukela ekungabikho komjikelezo wokugcina esikhathini. Yilokho okugqugquzela owesifazane ukuthenga ukuhlolwa kokukhulelwa noma ukuvakashela umjozi wezifo. Kukhona amathuba okungekho nemiphumela yokuqeda ingane emasontweni ama-3-4 okubeletha.
Kodwa-ke, noma kunjalo isithelo esincane emavikini angu-2-3, sesivele sinethonya elikhulu emzimbeni womama ngokukhona kwayo. Ama-hormone akhethekile aqala ukwabiwa okuzovikela nokusekela umntwana kulo lonke isikhathi sokubeletha, ukulimaza esifubeni, kungase kube nezibonakaliso ze- toxicosis yokuqala nokunye okunye . Uhlolo oluhle lokukhulelwa luba ngumthombo wesifiso sokwazi ukuthi ingane ibukeka kanjani njengamaviki amathathu nokuthi iyini.
I-fetal ultrasound emavikini amathathu
Ucwaningo oluthile lokuthuthukiswa kwentuthuko emasontweni amathathu alukhulumi ngandlela-thile mayelana nokuba khona kwanoma yikuphi ukulimaza ekuthuthukisweni, futhi kuqokwa ngamacala ahlukile:
- kukhona ingozi yokuphazamiseka kokuthwala;
- owesifazane uzwa ubuhlungu esiswini noma izicathulo ezivela emzimbeni;
- isifiso sokuphazamisa ukukhulelwa kanye nesidingo sokucacisa iminyaka yobudala emasontweni amathathu;
- izimpawu noma izimpawu zokunamathiswa kwe-ectopic yeqanda lesisu.
Iyini ibungu elibukeka lifana namasonto 3-4?
Ngalesi sikhathi ingane iyingqayizivele yezinhlamvu ezikhulayo futhi ezihlukanisa njalo eziqala "ukwakha" kumuntu omncane ozayo. Ubukhulu bombungu emasontweni amathathu kuphela ngamamitha angu-16 kuphela, futhi isisindo singu-1 gram. Izitho zokumbumbulu azikwazi ukulwa nokubonakala kwanoma yisiphi isici futhi zinikeza izinkinga ezingavumelani nokuphila kwamuva. Umntwana manje usebunje, futhi u-uzist onolwazi uzothola indawo ye-tummy noma emuva. Ikhala limelelwa yimibimbi, kunezakhiwo ze-auricles kanye ne-cartilages ye-skeleton ezayo. Ukuphela kwesonto lesithathu kubhalwe ngokubunjwa kwensimu yenhliziyo kanye nokuphambana kwayo kokuqala. I-embryo isesakeni elincane le-fetal futhi lizungezwe yi- amniotic fluid . Ngakho-ke, ngaphambi kokuba umama ozayo abonakale ebonakala kuphela endaweni ecacile esikrinini somqapha, okuzojabulisa ukushaya kwenhliziyo kuqala.
