Injection and cystitis

With the contraception I experience a lot of abdominal pains frequently

I felt like I was going crazy or losing my mind while on this contraceptive. I was an emotional wreck, I was not doing so well physically either. I had zero sex drive, so it did not make sense for me to be on birth control when I was not even having sex (markedly diminished libido).

I went on thsi injection due to my terrible experience with rigevidon, at first everything was fine as my skin cleared up, i only get the odd spot which is supported by acne medication- which was great considering i am acne prone. However it was beginning clear that i was gaining weight, I started off as a size 8 (very slim and petite) to currently being a size 14, leading to a size 16. My hips have also widened, this has led to an increase of SO many stretch marks, it has had an affect on my confidence due to this durastic change, while having the same diet the whole time. Yet this may be because i began at 16 now 18, coming into adulthood maybe?? At the minute my moods are terrible, i am very irritable, riddled with anxiety and more sensitive; so if youre looking into this as someone who has suffers with mental health I would not recommend. The pain of the injection is not bad however I am attempting to come off of this contracpetive as soon as possible yet just struggling which pill to choose due to my fear of weight gain, poor skin and loosing my sex drive. Just remember eveyones experience is different this is just mine :)
