My S/O and I aren't particularly trying. we don't even really think about it, to be honest. I haven't been on bc since I was 13 (I'm 21 now) and we don't use condoms or pull out. We are in a situation where we are able to be parents, so we haven't really taken precaution. But I'm realizing now, that even though we are 2 healthy young adults having sex regularly, unprotected, every month.. I'm still not pregnant? is there something wrong with me?
