twitches in uterus area

Anjelica • Mommy to a beautiful boy 💕
I have no idea when I ovulated and I've got about 2 weeks until AF. We had unprotected sex 8 days ago and I'm feeling twitches and things today. I've never felt this before. Only thing I can compare it to is tiny baby kicks! (Obviously it wouldn't be baby kicks but that's what it feels like)
Anyone know what it could be?!
