Ok so I wrote a huge thing and it didnt show up so im makin er shorter this time..

I had unprotected sex, the guy is clean and he went on my instaed of in me.. What im scared of is the precum that might of gotten in me. I wouldnt be so scared because I am on the bc pill but it is just that that recent week I was screwing up on my pilss like I was taking tues n wed on thurs and thurs and fri on fri.. I had the sex a week after my period ended. Which is worse cayse it is easier to get pregnant then. My question is.. Do you think im pregnant. Or do you trhink I shoudl go get the morning aftre pill. It hasnt quite been 72 hours.. So if yuou could help me out as soon as you can..
Like does it necessarily mean it was usles to take the pills all screwed up , or will it be ok because theyre in my system fighting off whatever they do yto stop you from gettin pregnant.. Thanks so much and help me out as soon as you can.Please, my tiem is runnin short!!! Thanks again!!!
