So on the first day of my last period I gave an ex oral sex im worried the semen on my hand was still there when I went toilet and I can't remember if I washed my hands or not before wiping myself after doing a wee could this get me pregnant? A week later in my fertile time I had unprotected sex loads of times in the space of a week with my current boyfriend and have just found out I'm pregnant..There is no possible way its my ex that got me pregnant from possible sperm on my hand when I went toilet is there? Just worrying really although i didn't have sex just gave blow job as opposed to having loads of unprotected sex with boyfriend?
