If i am not on birth control and i have sex. he finishes inside of me and the next day i get my period if i am not on birth control and i have sex. he finishes inside of me and the next day i get my period....is there still a chance i could get pregnant?"

Even : Even though it is unlikely that you would get pregnant having sex during your period, it is not impossible. If you are sexually active and not planning on getting pregnant, you should give your doctor a call to discuss birth control options for you. Below i've attached a link about the various options available.

No: A period puts a "period" on that menstrual cycle for conception concerns
