Well Sunday night the first day of my new pack he finished inside me. I panicked and bought my way the next morning about 9 hours later. Since I had my period about 8 days before this happened is there a chance I can be pregnant. I'm freaking out because of an upcoming surgery. It's been a week and my nipples are hurting and cramps. I know it's to soon to get all this but I will never let him do that again. Totally stupid of me. Please help. I'm scared.
