ive had sex once this entire month. i’m on birth control and always take it on time, never missed a pill ever. i had sex the day i started my new pack and my period is coming in about a week. i’m a bit nervous, i’m not sure why i’m so nervous because usually i’m not. we did not use a condom, but he pulled out and i’m on birth control. the night we had sex and about 3 or 4 following nights a took 1000 mg of vitamin C to try and ease my mind. does this seem like a high or low risk? am i okay?
