Don't worry of course you can become pregnant,with PCOS there are hormonal
imbalances so delay in pregnancy
,and when you hv taken krimson 35
the imbalance would hv decreased its just the matter of time,be stress free and try for pregnancy you will get the good news soon.
Would advice you to go for plain follicular study
to know the status of your egg developement and all so that you can plan the intercourse around the time of ovulation because as I said in PCOS nothing can be predicted so don't worry and all the best.
