Okay, so 5 days ago I spent some time with my boyfriend. I gave him a handjob. He touched his penis and had some precm on his fingers. After probably 2-4 minutes he fingered me but I quickly noticed that he didn't washed his hands so I made him stop. Maybe he wiped it up in my jeans and pants before that but we're not sure. My period usually begins faster, however it didn't. Due to my calendar it should start tomorrow. We were really stressed so I had a pregnacy test at home and it came out negative. But my boyfriend is still afraid because maybe I had it too early and not in the morning but afternoon. Is there any real chance of pregnacy? I'm actually losing my mind rn and tomorrow is the last day when I can use a pill, as they say it's working to 120h after the conception. Please, I need a fast answer.
