So is it safe to say my peak was CD 16? I tested the day after and my surge went down so I’m guessing I ovulated either cycle day 17 or 18? I take letrozole 2.5mgs days 3-7 of my cycle I’m on round 3 and my first round I had confirmed ovulation w/ progesterone blood draw & last month I didn’t opk at all but I’m pretty sure iovulated w no luck of BFP and now this month I got a positive opk I’ve had sex almost every day in my fertile window so I think I’m about 4dpo just waiting to test 🤞🏾
