Got a period but still paranoid about pregnancy?

So, I’m guilty of vigorously reading/watching stories of women being pregnant and not knowing, or how their implantation bleeding was similar to a period, and quite honestly, it’s been really freaking me out.

I suffer from pretty bad anxiety and it’s affecting my sex life. I’ve gotten two periods over the course of two months, so obviously, that means I’m not pregnant - but I can’t help but get stuck on those what if’s after hearing of those ‘I didn’t know I was pregnant’ stories.

The periods I got were normal - they both lasted a week, consisted of red blood with clots with occasional dark brown, filled up pads, and had that terrible iron smell, but I’m still so afraid and paranoid. I saw a post about a woman saying she bled three times before she found out she was pregnant, and that really did it in for me.

How do I stop feeling this way? I want to take a test so badly but I know deep in my heart that I probably don’t need to take one. The anxiety I experience literally every day has really lowered my sex drive, and I want to have a conversation with my boyfriend about abstaining from sex for a while for the sake of my sanity. I also would like to go on birth control, but I’m hesitant because it doesn’t seem right for me at this very moment.

Obviously, I’m a wreck. Thoughts?
