Ovulation bleeding or something else? HELP!

Sarah

I had a sudden “gush” of blood (sorry for the TMI) last night and that was it. Nothing more. Google is no help but ovulation bleeding came up but that sounds like it’s suppose to be just spotting?? I’m cycle day 13 and suppose to ovulate in 3 days. So I’m just really confused as to what my body is doing! 😔 has this happened to anyone else?
