I'm 18 years old. I am late on my period, based on my period tracker app I was suppose to get it the 20th of this month but I didn't. I thought I was going to get my period the 22nd because that's the date it started on my previous period, but I didn't. Today is the 25th and yet I still don't have it! I am really scared and stressed out because my boyfriend and I we were fooling around no vaginal sex was involved! It's going to be two weeks on Saturday since that happened. He touched his penis and then minutes after he started rubbing and kinda like fingering my butt which I am really scared about what if he had some sort of semen, sperm, or pre-ejaculated while he was touching me. Although he's not scared, he thinks I'm just overthinking, stressing about nothing and he's sure he didn't had No liquid in his hands when he was touching my butt. Is there a pregnancy possibility in this situation?
