What do you guys think....the last time I had unprotected sex was October 21st

Cycle has been off lately. I am sexually active , no I’m not stressed I don’t really care, and I haven’t changed my diet. I normally have a full flat tummy but this past week/ 2 weeks I’ve been bloated. I’m not exactly sure when my next period is coming now. Test came back negative. This is the second time I’m spotting in mid cycle expect this time it was more red, in November it was very light pink spotting. And no I havent had any bad cramps, just little tiny ones. I’m not trying but I’m not preventing so I’m letting things flow.

Symptoms I’ve been getting:

Dizziness

Hot flashes

Spotting(light pink) in November

Fatigue
