Ovulation Bleeding?! Help!

Hi,

So yesterday according to this app was my ovulation day. Me & hubby had sex, & after done I noticed when I wiped a little pink. Nothing else out of the norm, except my boobs hurt.

Flash forward to this morning, I woke up with quite a bit blood. And have been bleeding enough to the point to wear a pad.

Not sure if this is normal? Has anyone had this?
