So my dilemma is, I ended my period September 3rd and got put on my new birth control the 10th.I take it everyday around the same time, between 6-7 am. 8 days later today on the 18th my fiance and sex and he did not pull out. I was just wondering how much of a chance I would have at being pregnant. I'm 20 years old and a baby wasn't a part of our plans right now. Any helpful answers would be greatly appreciated. Thanks!
