I have obsessive thoughts about accidentally getting pregnant and it never leaves my head. It's been almost 3 months now and everyday I think i may be pregnant even though i didn't even take part in any activity that could cause this AND i'm on birth control. i'm paranoid about my stomach changing, though it's always bloated as i suffer from severe irritable bowel syndrom

My head is telling me everyday that i'm pregnant and that i have to perform things like buying objects and food i don't need or else i'd be pregnant

I have also started to punch myself in the stomach very hard a certain number of times which i know is too dangerous because i have had to deal with cyst problems in my abdomen for the past 5 years. I also took a big amount of ibuprofen as i've heard it prevents pregnancies . my rational mind tells me it is simply silly, but my OCD brain tells me it's true.

I can't live like this anymore. Please give me advice, my own therapist doesn't understand my train of thoughts.
