I'm 19, 160cm tall and at last check 55kg. It has been at least 2 months since my last period and even then my last one was almost non-existent. I have also recently started suffering from really nasty acne and somewhat abnormal hair growth. These are things I have never had in my life!
I was thinking a couple of factors may be to blame but I was hoping for advice from someone that has maybe been through something similar.
Firstly, about 5-6months ago I stopped taking the pill. That said even though my periods were really light after that, I was still getting them regularly for the first couple of months afterward.
Secondly, a while back (November-December?) I had to take the morning after pill. That seemed to really mess my body around at the time, is it possible that it could have done something to my hormones?

Also I suppose I should add that recently I did lose a lot of weight but I'm definitely not underweight. I'm also not overly stressed and I'm pretty sure I'm not pregnant.

Any advice would be great and very much appreciated!
