Since 3 months which is from march I am having my periods in every 15 days . In May, I've got my period period on 10th and then again on 27th and I'm still bleeding from 27th and today is 5th june it is 10th day of my periods. I have done my thyroid. Check and prolactin check as well, and it is normal. I have also done the ultrasound scan of my abdominal pelvis. Ans I have bicornuate uterus . Can you please tell me what is the cause of it because this has never happened to me before? Any medicine you can prescribe for this problem or any advice, you want to give me?
