Stomach pain

Adelia

So I’m a week and a half from getting my period. But I’ve been getting a tight pain in my stomach not cramps. It just feels so tight and it’s down by my uterus I can’t turn certain ways without it feeling like my muscles are ripping even having sex with my bf makes it worse it been happening for the last 2 weeks 🤦🏼‍♀️🤦🏼‍♀️ any advice ?
