Opinions/open minded people needed!

This is a little mini rant here! I am a little fed up with some women on here who shame the younger girls for being on this app. It is not just for pregnancy. It is not just for women 21+. As a teenager who is almost 18 I feel like I can sometimes be judged because I'm young. I don't want a baby but I have this app because I get my period and I have a boyfriend. It bothers me that some women get up In arms about young girls/women (12-18/19) having this app because it's for "couples who are trying". It's annoying! It's a great app for periods and instead of shunning those girls who ask sex questions at 13 we should be happy they are asking instead of just going for it. It's annoying as *word I won't use because it may offend people*. Just stop being so uptight about it please! If you're on the other side, could you maybe drop a comment as to why? Im just curious, and there won't be bashing because that's not rad. Okay rant over! ?
