Calm me down please 😅

My boyfriend and I have been together for a little over 2 years and I've been on the pill for a little over a year. Recently, we started to have sex with a condom and he'll finish inside me. My period is due within the next week (but sometimes it skips months)...
We had sex earlier today and when I went to pee after, there was some pink discharge (and blood) on the TP. Almost every time I went to the bathroom it was there, I also filled a panty liner with brownish pink discharge (?). I've read that implantation bleeding is barely noticeable and what not. I have no other symptoms of pregnancy. Am I freaking out for nothing and worrying myself sick?
Side note: this has happen once before but I think my stress delayed my period
Second side note: we aren't ttcÂ
