Doctor, I was prescribed derivy 10mg by my gyno as I got my period twice in the Month of July first for 2 weeks and there after for another 2 weeks. during the period of medication i did not get my period as informed and there after got my period once the medication was stopped. I got my period on the 5th of October which lasted for 5 days and i have now started to bleed a little bit again today. i am concerned and is this normal or should i visit my gyno again
