BV or yeast infection?

Hey I've been having thick white discahrge and a lot. At first I thought it was because I had sex with my boyfriend in the first time in a while and he came in me, I have an IUD. It's been a few days and sometimes i notice the discahrge has a little smell. I don't know what it is, and due to the current Covid-19 situation I'm scared to go to the doctor. Please help🥺👉👈 and if theres anything I can buy or use to help clear whatever this is, up.
