Anxiety?

(Please read the whole thing I’m explaining a bit. I promise it’s about anxiety)

So Ive been on the Nuvaring for a month and am in my second ring and had sex during the second week of it when the condom broke. I put it in the first day of my period and he didn’t ejaculate in me and there wasn’t any obvious Precum. I’ve since had my (heavy bleeding with super tampons) withdrawal bleed and took two pregnancy tests about 4 days after my period ended and they were both negative. I’ve noticed skin tags on my boob and veins in my chest and thighs but I lift weights. It’s like I know I’m not pregnant but I can’t help but obsess over my body and whether this or that is a symptom of pregnancy and I hate it and don’t know what to do about the anxiety and how to calm down because I’m not pregnant.
