I have PCOS. It takes me ages to conceive, but it does happen. 2.5yrs for #1, 19m #2, 11m #3, 12m #4, 3m #5 (miscarried at 12wks)... been trying for 6months this time and no luck so far. (All conceived naturally)
People with PCOS conceive all the time. However it may be easier for some people to get pregnant than others. Good luck and seek medical help if necessary.
