I worry about getting pregnant again so soon after just having my baby. I'm not having sex right now, but when I do I worry. I try to take my pill everyday at the same time but sometimes I get side tracked😶 and My period is all out of whack so I can't rely on that either. I just pray that when I start having sex again with my sons dad well we don't get pregnant 😰
