Fertile cm 2x 4 days apart

Kristina

Hey guys! I’m on cd 26. I have a 28 day cycle and should start Monday. This month I noticed I had fertile cm twice. Once cd 13, 14, and 15.. then dry for a few days, then watery clear gushes of fertile cm again on cd 18/19. Does that mean I ovulated twice? I took a frer today and BFN, so clearly if I did ovulate the first time it would be positive by now. My breasts haven’t even started hurting yet.. like what’s going on?

Thanks!
