Sudden random pain in my pelvis. it feels like full pressure, can somewhat feel it in my lower back. i have pcos and just started 1000mg metformin?

Ovulation: or larger cyst, if pain worsens, see your doctor you should become more likely to ovulate on the metformin, other measures should be included such as clomiphene, if you wish to be pregnant

PCOS: With PCOS, periods are few to absent. Type II diabetics can sometimes revert to somewhat regular cycles with treatment to regulate blood sugar. Most often, the symptoms described are due to bladder or pelvic infection, and you should see your gyn physician for an exam to determine the cause. It may also be ovarian in origin. Hard to tell with the history given.
