Painful intercourse :(

Well, I've been dealing with something bothering my vagina, not sure what it is. I've been treated for std just in case but test came back negative. I had a weird smell, painful sex etc now that smell has changed to less worrisome smell, more neutral I guess, but I still have a really "closed" vagina... I was also treated for an infection and I'm still having a large almost of discharge, and a closed vagina....
​This is making ttc really difficult, and frustrating not only that but my sex drive is fine but I'm unable to enjoy or want to have sex :( 
​Please help, any suggestions?
