I had unprotected sex with a friend 6 times in a 72 hour time frame. he pulled out every time. it was planned or anything and I have been single for a while now so I haven't been paying attention to my cycle as much. I got this app today and found out that during that time I had just started my ovulation days. I'm worried I might be pregnant because he lives 3 hours away and neither of us want to move. I mainly just need advice.?? could I be pregnant?
