I had unprotected sex and he pulled out before he finished but there were some leaks, the next day I got my period and I took the morning after pill( next choice one dose) and I'm scared, I don't know what to do, my period seems normal but I still don't know what to do!!

Having a period is natures way of mourning another month with becoming pregnant. I think you're fine.

It might be a good time, while this is fresh in your mind, to consider alternatives to the morning after pill, an emergency contraceptive, and the withdrawal method of birth control. To be clear withdrawal isn't effective. You're still putting semen in the vagina whose sole purpose is to knock you up. Considering the lengths that you've gone through to not be pregnant I am assuming that you want to continue to be not pregnant.

Condoms at least should be used, even if this is your long term partner, and another form of birth control as well, the hormone pill, depo shot, nuva ring, or what not. These will lessen the chance of becoming pregnant to a near imposibility. Please note though that whenever you have sex you have a chance of becoming pregnant. It is just mitigating that to a 1 in 1000 chance instead of a 1 in 10 chance.
