mysterious bump

In august I noticed a bump grew at the bottom of my vaginal wall and between the anus. I thought it was a piece of poop stuck because I first noticed it when I passed a bowel movement. I was literally straining but it wouldn't come out so I tried suppositories and even trying to stick my finger up there to get it out LOL. I thought it was a hemorrhoid too but when I went to the doctor he said it wasn't. I saw a gyno at this urgent care and she said it was just swelling and that it looked herpetic because I have cuts but I knew that was from me scratching from all the itching. I knew it wasn't swelling because it is hard not tender and it's a different feeling when I touch it with my bare hands and her touching it with gloves. She tested me for stds but she never called me with the results I even called to get them but they never called back. She said it was either herpes or a horrible yeast infection so she gave me meds for herpes and a yeast infection pill. I never took the herpe medication but I took the yeast infection pill and after a day or two the itching and cuts went away. The bump between my vagina and anus never went away it's been there for 10 months. It doesn't hurt unless I have sex in certain positions and it doesn't itch either. I know those urgent care doctors are wrong because it is still there. I think maybe it could be a cyst but I don't know. Again the bump is at the very bottom of my vaginal wall. It is between my vagina and anus.
