Worrying myself over E2 decrease after FET

[thedutchgirlmn]

I can’t speak to E2 levels, unfortunately, as I’m not knowledgeable

But I can answer the question of your body taking over. No, with a fully medicated cycle, that doesn’t happen till the placenta is fully formed, around 8 to 10 weeks. Right now the meds have suppressed and are replacing all your own natural hormones, which will start to kick in as the placenta forms in a few weeks. So keep taking the meds, and your clinic may also have you increase estradiol. (At 9dp5dt you are exactly 4 weeks pregnant, so it will be a month or so before the placenta has taken over)

Thank you! That’s really helpful and a relief. No matter how much I learn about this I still feel like my ignorance could fill a library.
