Will a fall in progesterone and estrogen levels disturb implantation?

Question

Hello doctor,

I have done a FET transfer cycle before ten 10 days. My hCG pregnancy test is tomorrow. Are nine days too early to test? My other real concern is that on the day of transfer, my estrogen levels were 223, and progesterone was >40.0. Before four days my estrogen levels were 106 and progesterone was 35. I am still currently supplementing both Estrogen (Estrace by mouth twice a day) and Progesterone (PIO 0.03 fl oz IM once a day, and Endometrin suppositories twice daily). Does the drop in both hormones indicate that implantation did not take place? I find it unusual for both levels to drop simultaneously, especially while supplementing.

Hello,

Welcome to icliniq.com.

Usually, the levels of estrogen and progesterone will increase from early pregnancy to the third trimester. But often there will be some range of the hormones according to the gestational age. Though the levels of hormones little decreased in your case, they are still in the normal range according to the gestational age. Like during four to five weeks, the progesterone levels should be 11.2 to 90 ng/ml. And estrogen levels should be 100 to 400 pg/ml. So, according to this, your levels are still within normal limits so better to follow the course advice to your gynecologist and undergo hCG test as advised. I hope I have answered your query, and I will be happy to answer any further follow-up queries.
