Me & my boyfriend started having sex Friday, he used protection both times, before everything happened we were dry humping and he was wearing a condom he ejaculated into it but changed it before we actually started doing anything. He did not ejaculate again while we were having intercourse. The second time he wore a condom and ejaculated but pulled out as well. . . I am on the pill but I might have missed three pills I made up for them all on one day which I know I should have not done that. I was suppose to get my period Monday but instead got it on a Tuesday. . should I be worried? it lasted until Thursday and all day Friday I had like the after math of having your period like the really dark blood that noting really comes out? today is Saturday and on my underwear there is a little bit of light blood on my underwear, I am worried about pregnancy, but I don't think I should be, should I?
