AM I PREGNANT?

Alright so i’m freaking out i haven’t got my period for 5 days even though i have irregular periods but i’m afraid something is happening to me.

so my last period was feb, 20th and I experienced a very red even dark blood period for 7 days. after couple of days, my boyfriend and I got frisky and had manual sex with me giving him a blowjob until he came. afterwards we went to the bathroom to clean up but then he fingers me. i’ve no idea if he has semen on his hands, and I also sat on his lap but we rinsed off any semen in that area before.

so heres my QUESTIONS!

1. am i pregnant???

2. if theres semen on his hands and he rinsed it off in the water will it die/not able to fertilize?

thanks!
