Need A Little Help/ Advice

🌻

I got my wisdom teeth removed 1/12/18 before that I had some light bleeding a week before my period because I’m on the pill and it’s normal, so I most likely got my period early. I’m a little scared because i have to stop the pill for this surgery. I had sex with my SF other last week he came in me twice 🙈🤦🏻‍♀️. I know this is us being very immature, now I’m having sore breasts, light cramping, nauseas here and there tiredness but I wiped after going pee and I smelled a little iron..:... not sure if it’s my period or pregnancy did y’all have the same symptoms before periods???
