I was recently seen by a gyno who said I might have PID or endometriosis. They prescribed me an antibiotic and since then I've noticed I've had a yellow discharge. It smells kind of musky and salty. I've been tested for STDs and came back negative (got tested within the past few days just in case) and I'm not sure what the cause is. I've had BV before but this doesn't feel like BV or yeast. What could it be? Please help.
