My periods are always regular. My gyne give me Diane 35 to help my periods cycle. On 30 oct I start having brown clotting than it converted in to rich blood clot so I start taking pills . As told by the Dr (start taking pills on first day of menses)after 2 days the clotting stop completely and the white fluid starts coming normally!!!
What should I do?? Should I stop taking pills?
