Longest cycle before IUI?!?!

DJ

Anyone out there have a really long cycle before <a href="https://glowing.com/glow-fertility-program">IUI</a> ? I’m currently on CD 17, the doctor had me go back on letrozole on CD 14 and take 5mg instead of 2.5 because my progesterone was low. I go back I’m for another ultrasound and bloodwork CD 21. I’m getting so impatient! Trying to also BD often this week just Incase I ovulate. I’m scared and anxious and really need some reassurance
