Aw hun! When I first started having sex, I looked up a lot of ways to get pregnant and was super careful. Pills aren’t always effective, it’s good you know you need to wait before having sex again while on the pill. He clearly had no idea what he was talking about. Despite pulling out before he cums, there could still be sperm in pre cum which can cause pregnancy. He shouldn’t have convinced you if you wanted to use a condom, I personally think that’s very wrong. If I were you, I would tell him. But it’s all up to you with which option you’d choose in terms of the pregnancy.
Goodluck! Tell me how it goes or if you need to talk to someone xx
