I Missed my PMS cycle ones (around start of January 2016) after that my Weight started to increase and belly fat increase. Hair started to grow under my chin area. My cycle date changes like 2-3 days before or 2-3 days after the due date. Is there a serious issue? As I haven't gone to any doctor yet if i have to which doctor i have to go to, as i have no idea which type of doctor will resolve this. I had been using Atractin tablet for my acne from November 2016. And my weight has reached to 65kg from 60kg from January 2016 to now. My body is mostly swollen. And making me really worried.
