My girlfriend and i rubbed our genitals togeather but i know that i did not ejaculate near her, not even at all. But i am worried about pre cum, i never put my penis inside of her vagina, i am just scared that the pre cum may do something. we did that on the 4th of august i am pretty sure, and today the 7th, she started taking birth control pills. Do you think that she may be pregnant? i am soo scared.
