Rebecca • Mother of 2 beautiful baby girls. Conceived with PCOS🎀🎀

Ladies I have pcos and I am 6 weeks pregnant with number 2. I had to be put on progesterone with number 1 and my levels went from 5 to 19 in few days. This time around it's taking lot longer. I was at 8 then 13 within 4 days. Then I went to 14.5 within another week and back down to 13. I am on progesterone pills why is it decreasing?! Anyone have this issue??
