Help!

I have had yeast infections, bvs and utis before in the past so i pretty much know the symptoms when i have one of those. But now i have this yellow discharge coming from my vagina and im pretty sure it’s an std. i’ve never had this symptom happen to me. It is odorless and does not itch. i did have pelvic pain and a little bleeding. it does hurt when i urinate. has anyone else experienced this issue? im going to get tested this week. i suspect my boyfriend is cheating but not positive.
