Co se děje po početí?

Krátce po početí tělo ženy začne produkovat hormony, které jí pomáhají s přípravou na následné nošení a vývoj plodu. Jedním z prvních hormonů je HCG (lidský choriový gonadotropin). Tento hormon se váže na vznik placenty a v těle ženy se objevuje už na začátku těhotenství, tedy po početí. Jeho hodnota nějakou dobu stoupá. V případě jednoho plodu je v moči patrný zhruba týden po otěhotnění, samozřejmě čím je doba delší, tím je i výsledek diagnostiky gravidity (příp. těhotenského testu) jistější. Pokud jde o vícečetné těhotenství hodnoty HCG jsou v krvi i moči vyšší, to však žádný test neurčuje. Kolem čtvrtého týdne (hodnota už je značně vysoká), může tento hormon způsobovat těhotenské nevolnosti, které by měly ustoupit po ustálení hladiny HCG.
