I’m currently on CD14. I have completed 5 days of Femara starting on CD3. I just had my follicle check on CD11. My RE said for me to trigger on CD15 between 10pm and midnight. With IUI scheduled for CD17 at 2pm. My question is regarding the OPKs. I’ve been testing twice a day without any test line showing. This morning, I saw a faint line, and by tonight, the line was much darker (but not dark). What have your OPKs looked like day of the trigger shot (but before the injection)? My fear right now, is that I’m going to ovulate too early and miss our window.
