something might be wrong

about a month ago my boyfriend and i were having sex like everyday sometimes twice a day, my vagina started feeling like raw idk how to explain it but it hurt and it wasn't like a sex hurt it was like a something's wrong hurt. so i told him we needed to take a little break, a couple weeks after that it was still hurting but less, and then i noticed some colored discharge so i looked it up but it wasn't smelly or itchy, but a couple days after it was smelly and kinda hurt when i went to the bathroom, so i told my friend about it and she said i probably have a yeast infection so we went to the store and got vagisil wash and the cream, i used that for a week or so and it was fine so i stopped but a couple days ago it came back, should i go see a doctor? or just keep using the cream and wash?
