Of getting pregnant from sexual intercourse if he was only in for less than 10 seconds and didn't ejaculate. Also, we are assuming there was probably some pre come. Moreover, at that point in time I had just started the pill and was on my 9th day of taking it. That was almost 2 weeks ago and I havent noticed any signs so I was wondering if I should expect any changes soon. I am also due to have my period within a week and i'm very nervous.
