Vaginal dryness? Help?

Ok so ive had this awful vaginal pain for the last two or three days. It feels like cutting/burning/aching. I havent had any itching, no painful urination, and very very light discharge, and no funky smell. I am sexually active and I am on nexplanon. I havent had my period because nexplanon stops them. Im a victim of molestation and going to the gyno is out of the picture for me. The last time I went, I threw up and I had multiple panic attacks. Any tips? Anyone know what this could be??
