At that situation i was not able to do anything ,so much pain ... I was not able to poop at that time . Now it as been 2 months (today's date 19/2/2021) ,my menstruation process as not yet occurred... For this situation what I should ... I went and consulted  so many doctors bit there's no result .,it's just repeating .
