Should I be worried?

🤘

So I do have unprotected sex but I’m on the pill and lately I’ve been really hormonal and moody, my breast (mostly nipples) have been sore, I’ve been getting aching headaches and really bad cramps. I know for a fact it can’t be my period or the time my period usually comes bc I’m on the pill and I control that 😅 I know that the pill isn’t 100% effective and my mum keeps joking around saying I’m preggo😂 Could it be a possibility that I’m pregnant or is it just getting to my head???
