Would my mom b able to tell?

I hate to make assumptions about people I don’t know and situations I don’t fully understand- but I’m going to go ahead and say that your mom probably already thinks you two are having sex. If she put you on the pill, even for period problems, she probably assumes the two of you now feel safe enough to start having sex. Moms were teenagers once too… I don’t personally think that 16 is ready- because should you get pregnant (my cousin got pregnant once with the pill, once with the nuva ring, and once with mirena) on birth control, you cannot financially or emotionally support a child. That’s why I think It’s best to just WAIT until you are a little older. Plan for those “what if’s” in life, ya know? KUDOS to you for waiting already. It takes a strong moral compass to overcome physical urges. When I first had sex, it wasn’t entirely consentual, and it wasn’t painless because I wasn’t ready. I did have quite a bit of swelling, bleeding, and pain afterwards the next day. I walked like I was saddle sore from horseback riding all day. I avoided my parents, (I had an unwarranted sense of shame), but my friends were able to pick up on it. I don’t think that you would walk weird unless he was unnecessarily rough with you. I don’t think anybody would notice under normal circumstances.
