I'm on my third Metformin refill for PCOS. I'm about a week away from starting my period (my second one on Met), and I've noticed a larger-than-usual amount of discharge. It looks, smells, and tastes normal (my husband confirms this). We had a quickie this afternoon and we both noticed that I needed very little foreplay to become lubricated enough for penetration, whereas I usually need a good bit of it.
I have severe anxiety over health-related issues (I'm working with a psychologist for this), so it's possible that I'm reading too much into a symptom that most people don't give a second thought.
Anyway, do any Metformin users notice this? I would ask the PCOS board that I usually visit, but everyone here is so much more knowledgeable about these types of things.
