PLEASE HELP ME CALM DOWN

DISCLAIMER: I know the chances are little to none but i need reassurance because my mom keeps making sly comments about me being pregnant

Here’s the run down. I started birth control on June 2nd. I waited the 7 days to have sex without a condom. After 9 days, I had sex without a condom. He peed before so there shouldn’t have been any cum in the precum and he didn’t cum inside me. Literally 20 minutes later, I had stomach/digestive issues, which is a common side effect of the pill. I also had some before that too. I’ve had sore breasts too. What are the chances these are pregnancy symptoms and not the pill symptoms? I’ve had no back issues, peeing frequency is normal, and no headache.
