Urgent !! I’m freaking out lol

Victoria

I had unprotected sex on the 16th of this month and my app said my fertile days were the 13th-17th. My period if supposed to start on the 1st of March...but my boobs are hurting so bad! That’s usually the biggest period symptoms I have about a week before I start. I also read that can be a pregnant symptom...but if I was pregnant, I wouldn’t be having symptoms this early would I?? Like it’s only been a week. I’m pray to God I’m not pregnant and these are symptoms of my period getting ready to start. What do you think?

Update: I’m not asking your opinion on if you think I should be having unprotected sex or not. I’m asking you if you think these symptoms are my period coming or pregnancy?
