INFECTION? Help pls

Hello. In march I started to have heavy itching in my vagina after I had unprotected intercourse. However due to the pandemic I wasn’t able to visit a doctor. It’s been 2 months and the symptoms don’t get better. Plus, now I have a lot of yellow-greenish discharge every day and the itching continues. I have no clue what this is, and i’m scared it will have complications but I really can’t get out of the house bc of the pandemic. Any tips? HELP PLS
