Very paranoid...😰😰

Ka

Alright so, on Friday (my birthday 😊) my SO and I had unprotected sex, but I was on my period. It was a light period that only lasted 4 days. My fertile window starts tomorrow and I ovulate on the 25th. I’ve been feeling very nauseous today. I know that sperm can live inside the body between 5-7 days, so I’m concerned that it could be something.
