Question : Just wanted to get a definite answer on when the placenta starts to take over the production of oestrogen and progesterone so I can be sure when it is safe to stop taking all my progesterone and oestrogen supplementation. I am at 11 weeks now.

Brief Answer:
It is safe to stop now

Detailed Answer:
Hi,

Placental take over and production starts completely at 9 weeks pregnancy. You don't need any more supplements of estrogen and progesterone after 9 weeks.

At 11 weeks you can safely stop all progesterone and estrogen supplements you have.

Let me know if you need any more clarification.

Regards
