HELP?!?

me and my fiancé had intercourse about six hours ago and since then i've had pretty severe vaginal pain and have been bleeding quite a lot but its really watery. at first thought it was just watery cm with spotting but its been constant for a while now. i missed my pill last night, and im ovulating. could this be related?! or has anyone had anything like this before?! what can i do?! i dont want it to stop us having sex but it hurts 😭 any advice???
