Feels like I keep starting my period?¿?¿?

So I’ve been having slight cramping that stops after a few seconds for a few days off & on, but that started 1.5 weeks before my period. My stomach feels super tight & it makes it hard to fall asleep because I randomly have trouble breathing. I had sex during ovulation, & a few days ago there was the littlest bit of pink when I wiped. My period is now in a week & I keep feeling like I start my period but I go to the bathroom & sometimes there’s nothing, & sometimes there’s discharge. I never get “period” symptoms almost 2 weeks before my period, only like 2 days before EVERY TIME. I don’t know what I’m asking but can somebody leave a sister some comments😩
