TMI!!!!

Ok ladies, I had laparoscopic surgery last month and had a cath in during surgery. Fast forward to May 5th, I had a saline sonogram done with iodine for my "practice" retrieval for <a href="https://glowing.com/glow-fertility-program">IVF</a>. Since my sono I have had slight brown discharge and have been itchy. Thought it was from the sono and iodine. Fast forward again to today, I finally had to see for myself what was going on. I have what looks like to be a sore in my vagina and my urethra has this small white looking mass on it. I am clean and have been tested this past month and since my surgery I have not had sex. What do y'all think this could be!?!? I am freaking out. Calling the Dr. tomorrow.
