Discomfort during sex..

Layla • Layla ❤️💛💚💙💜
Hello,
I'm hoping someone will help me. My period is due a week tomorrow.
I've been cramping all day & just DTD with partner and it feels well... err, different. Like he's bashing into my cervix. Sorry TMI.
I've had a lot of watery disharge too.
Boobs hurt (they normally do before period) - do you think these are signs? Or again, convincing myself 🤔🤔🤔
