Okay so I’m already a single mom of 1 who is currently 6 months old. Well his father & I hooked up once, & boom I got pregnant AGAIN. But he’s now saying it’s not his because I took a plan B 3 hours after we had sex. But I know it’s his because I haven’t slept with anyone else in the last 3 years. So even though I took a plan B there is still a chance to get pregnant, right?
