TMI! HELP! Discharge 😫

I have had this discharge for a few of days now. I don’t know what is going on?! I am one day post ovulation, but I am having a dull tingling cramp feeling in my lower pelvic region ( I think that’s the area, right about the beginning of the vagina v shape). I’m also having some lower back pain and I am extremely nauseous. We have been having a lot of sex (TTC). Anyone know what could be going on?
