Hi, I'm just asking but okay... Sooo has anyone heard people say that if you live with another women both pms fuck up.. Okay so some info my mother has had 4 periods in the last month my mom is on a ring to help her period regulat, well since then my periods are not on track it's the 28th and I've not have one. Yes I'm sexually active.. I'm just worried if I may be pregos or could my moms cycle has fucked up?! Idk what to do or say about anything 😔
