Ovulation question

Tara • 25 years old. TTC #1 since 7/2018 with my husband of 3 years. ❤️

What are the chances of getting a positive OPK each month but not ovulating? In the 7 months I’ve been TTC, I’ve gotten a strong positive OPK on CD14 every single month. However, my doctor (in addition to the CD3 testing that I already did that came back fine) wants to do a CD21 progesterone test to “make sure I’m ovulating.” At first I wasn’t worried, but now I’m seeing that it’s possible to get positive OPKs and not ovulate. For reference, my cycles are ALWAYS exactly 28 days, and I definitely have signs of ovulation (EWCM in my fertile window, sore boobs in my luteal phase, etc.) Am I most likely ovulating? I did try to take my BBT several months ago, but I’d often forget, or I’d end up using the bathroom in the middle of the night and never get an adequate amount of rest before taking my temperature.
