Any ideas?

Becca

My luteal phase is usually 12 days (11-13). My cycles have been a bit off lately and have been 27, 38, 28, 30 and 33. I️m currently on day 40, just got a BFN, and I️m on day 15 of my luteal phase based on when I️ got a positive OPK. A lot of CM, but cervix is generally lower and more firm than when I️ was in my fertile window. I️ wanna just get my period so I️ can try again..... any ideas what’s going on??
