Anna, I'm contemplating IVF with Check and I'm doing a trial run with meds this month so see how I respond, so let's keep in touch.
FSH 77 is high of course but unless it's at CD3 it is a less useful number since our FSH always spikes before ovulation. I have been on estinyl for about 7 months and it's been very good for me. My FSH is gone down to normal and my antral follicle count has quadrupled most months. Not everyone responds that well so it will be interesting to see if it helps you.
You'll get more used to Cooper's OOT system as time goes on. It's a super quirky place for sure. Good luck to you.
