Do u think I’m pregnant??

So basically I had sex w condom and I’m on the pill but missed one 6 days before I had sex. I’m almost positive he didn’t finish because we were interrupted before and I’m almost positive the condom didn’t break. However my period was 6 days late and I had a normal flow first day and now it looks like old blood on my third day. I usually have short periods. I took 2 pregnancy tests 2 days after my missed period and it was negative. My pills could also have been off this week bc I left them in the heat so that could’ve affected my cycle maybe. Period medicine has also helped my cramps. I just want opinions before I test again.
