okay so i’ve been on bc(the combo pill) for 8 months, i rarely miss a day and the last time i did was a month ago, i just finished my placebo week and am on day 3 of regular pills, tonight i had sex unprotected but he did not cum in me, he pulled out. i take my pill at the same time everyday, how high is the chance of me being pregnant i’m freaking out and need advice
