Bleeding and ovulating???

Karah

So Friday I had a Hysterosalpingogram to see if I had blocked tubes (I don’t thankfully). It cause a butt load of cramping but all in all went great. My husband and I had sex that Sunday after, and every since I’ve been bleeding like period amounts, except AF isn’t due until the 20th. Well just for giggles I took an Ovulation test since I was supposed to start ovulation today and it says I am ovulating... sooooo what’s the bleeding from?
