Yes, my doctor also told me it takes over completely by week 12, which is when the morning sickness usually starts getting better for many. I am currently in my 14th week and feeling a bit better. How many weeks are you right now?
I have been reading up a lot on this, and I think it starts forming very early and is fully ready by the 12th week. It is so fascinating how our bodies prepare to nourish a new life. I hope to experience this beautiful journey soon too.
Oh, I used to worry about the placenta functioning properly day and night! It starts forming early but is completely ready around the 12th week to give the baby nutrition. If you ever feel worried, just ask your gynac during your scans, they explain it so well.
It starts developing really early, but it fully takes over the job of supporting the baby by around week 12 of your pregnancy. So don't stress too much about all these technical details, okay? Your body knows exactly what to do!
The placenta usually starts forming right after implantation and is fully functional by the end of the first trimester, around 12 weeks. After my IVF journey, I was tracking every single detail, so I know how anxious you must be feeling. Sending you lots of love and prayers.
