I am a 31 year old female. I had my second girl child on aug 30th 2015. It was also cesarean. After my 2nd delivery, I had my first menses only on march 14th 2015. During that menses, I had heavy bleeding. And after that until now, the periods hasn't come. Is there anything to worry for me? I had my pregnancy test last week. But it was negative. But still, is there a chance of me being pregnant? or is there any other reason? for cesarean, is there such chances of irregular periods? should I take any medicines for menses to come early? I humbly request to please clear all my doubts.
