Abnormal discharge...a lot.

I’m a little concerned bc for two weeks i’ve been having abnormal amounts of discharge. i thought it was from ovulation but i’m done ovulating for the month and it keeps making just a huge mess down there. it’s whitish clear, a little chunky/stringy. Sorry for being disgusting but i’m wondering if that’s normal. Also last night i had some that was yellowish with a little bit of blood. That’s when i got concerned. i don’t know if it’s an infection but i’ve been taking monistat to see if that will help. One more thing about my situation is that about a month ago I was having sex with my boyfriend and it was extremely painful. Like it stung down there and I started to wonder what was going on! Anyone think they have an idea?
