Help!

Hi all! My husband and I have been TTC for about 6 months now. It’s been hard because my ovulation is inconsistent (my doctor told me that I might not be ovulating every month but we need to try for 6 months before we do blood work to determine if I am or not and start medication). In addition to the inconsistent ovulation, my period is irregular. So according to my app, I am currently 12 DPO (I never got a positive OPK, but this is when my CM was most egg-white like) and 3 days from my expected period (as predicted based on my other cycles, because again, I’m super irregular). I took a test 2 days ago and it was for sure a BFN. But I took this one this morning. What do you guys think? I’m praying it’s positive. I’m planning to take another one here in a while. Any suggestions?? Thanks in advance! I appreciate the feedback!
