i am having PCOS.... i got my periods on 25th nov... and it was normal... it lasted for 8 days and stopped. then agaon i got my periods on the 1st of december. The bleeding was heavy.. with no pain...due to heavy bleeding i was given Dicynone 500 for 5 days... and Primolut N to be taken 2 times a day for 10 days. My bleeding stopped as soon as i took the pills. However i continues to take the pills for the said dates. once the medication was done i got my period after 4 days. now im on my 2nd day and the period is heavy with abdominal crps. i was given meftal 500 to be taken 3 times a day after food. I have just taken my first pill for the day. Please advise what i should do....
