I got the jab for the first time and all was fine, my periods seemed to be normal, the bleeding was very slight but lasted about a week and a half. Normal would be 3 days (of agony). I decided shortly after taking it, the jab wasn't for me, there was weight gain and acne and my moods were awful. Towards the end of the 3 months I got my period, but this time it went longer than 1 and a half weeks. It went for 8 weeks before I went down to the doctor. She said that everything was ok and it was just a side effect. I'm now on 13 weeks and still going strong. But it's really hard and I'm not sure if everything is ok. I get insanely bad cramps like I can't even move. Can my ovaries be getting damaged by this? And is there a way this can be stopped ?
