Ok so me and my girlfriend had sex for the first time on the 16 of this month. We both were virgins and I had a condom on. I didn't cm inside her but as soon we were done, When I got up the condom popped and she hasn't had any period symptoms. She is so on the 20th. Could she possibly be pregnant or is it just a period delay. (I didn't pre cm in the condom the inside of the condom was dry). Thank you
