Anytime you have sex you can worry if you are pregnant. No birth control is 100%, so if you are having sex you should make sure you are ready to handle what comes with sex... babies.
firstly wait until ur next period.. if u miss ur period den take a home pregnancy test after a week of ur missed period!! tht will conform if u r pregnant or not!! also see for ur ovulation calender... tht will help u track d chances of being pregnant!
If you have a GYN I would suggest that you make an appt to go see them and get tested. If you aren't pregnant you and your doctor should talk about the best form of birth control.
Best of Luck!

I hope I don't offend you, hun, but you're so young...a girl your age shouldn't have to worry about pregnancy scares. Sounds like there's a chance you might be pregnant. I hope that you're not, but if you are, my advice is that you tell your parents right away because you have to do it eventually; might as well get the hard part out of the way so you can relax for the rest of your pregnancy. Take a test when you miss your period and if it reads positive, get to the doctor right away so that you can get started with your prenatal care. Having a baby is a huge responsibility, but also the most beautiful thing in the world. Best of luck to you.
It is very likely that you are pregnant if you are not on birth control.
If you had a normal regular period, and had sex three days later . . . that would be on day what of your cycle? Count from the first day of your period, that's day 1. Did you have sex on day 10? It's likely you are pregnant if that's the case.
I don't know what "semen leaked out of the base" means, and I don't think you could have not noticed he ejaculated twice, and that you would have to get that information from him by asking if that's what happened.
