One day late?

Glow asked if I started my period today. Guess who didn’t? That’s right me. But no bfp, yet. I was cramping so bad one day after ovulation I assume. And I stayed cramping pretty bad until yesterday, I also had so bad headaches. Up until yesterday. So what do y’all think? Aunt Flo coming or do I have a chance. Should add I’ve been nauseous since about 6 dpo.

Since I’m getting negatives I’m assuming I ovulated late if I did get pregnant this cycle. Fingers crossed 🤞
