Period Help!!

Okay ladies usually my period comes between day 31-32. I'm on day 33. Last week I was having some spotting but it wasn't in my underwear only when I wiped after I peed.  But on day 31 hubby and I BD and his penis hit my cervix and it hurt and I jumped. The pain subsided and we finished. But when I got up there was a lot of bright red blood so I thought I got my AF but I haven't bleed since. What are the thoughts here? Btw my boobs hurt like crazy and I took a test on Saturday morning and it was negative.
