Cramping 2 dpo

This is my 3rd month TTC and my first month tracking BBT. Temps are saying I ovulated 3 days ago and yesterday I started cramping. I felt ovulation cramps on my right side the other day so I know it's not that. It's more of a dull consistent cramp and it's not on either side, it's like a uterine af cramp without the twinge feeling and it's been about 24 hours now. This isn't normal for me. Has anyone else felt cramps 2-3 dpo and gotten a BFP? If so how long did the cramping last? Could it be anything else?
