So I've had blood tests in the last few weeks. Day 2, 9, 12, 14 (today) as part of my "assessment cycle" at the FS.
Day 2 bloods - levels at baseline.
Day 9 - levels rising. Got told to time bd that day (wednesday).
On day 12 (thursday) estrogen levels were 1190. I had a pelvic ultrasound that day and the lady saw a follicle in each ovary and said it looked like i was about to ovulate. We bd that night.
This morning (day 14) blood tests showed levels were 300. The nurse rang and said I had ovulated already (on thursday or friday) cos of the drop in levels but I didn't get a chance to ask her if we should bd today.
A bit confused. Sorry it's late at night. I just hope that we caught the egg and I don't know if the levels dropping means we should keep bd'g or if that conception window is now closed.
