Water breaking after sex?

I’m 31weeks and just had sex with my man... when I stood up there was a little liquid which was to be expected and then I felt a weird gush of liquids after that didn’t seem like the normal sex liquids (I’m tired and semi worried sorry about the horrible wording). Then when I wiped there was a little blood that seemed different than just spotting after sex. Is that normal or is there anything I should do??
