It is common in PCO to have intermittent spotting.Breakthrough bleeding
is a common phenomenon with duphaston
. The chances of getting pregnant only with duphaston are remote in PCO, as ovulation failure is the reason of infertility
here. Your symptoms suggest progesterone
induced water logging. I suggest you to undergo proper evaluation and treatment with a gynaecologist as PCO has a very good chance of getting treated.Good luck.
