So I tend to always worry I’m pregnant when my boyfriend and I have sex. We use condoms and as far as I know they have always worked fine. I’m 17 and my period is irregular, but I get my period at the end of the month. It’s the end of the month and my boobs usually hurt a week before my period and they don’t. And I tend to convince myself that I have a “bump”. But then I hear of people having sex with no birth control and they don’t get pregnant. This is kind of just me venting but should I be worried? Or just calm down and trust that I’m young and my body/cycle is irregular?
