Does injection cause cystitis?

I’ve been taking the pill for over 7 years and wanted to try the injection for convenience of not worrying about taking a pill everyday, for that it was great no periods no more cramps, however I found too many side effects which overrule the one positive. - The first month was great, however month 2 and 3 I suffered with what I thought was recurring thrush but I went to the gp and did swabs but everything was negative with no infections, turns out to be vaginal dryness which are the same symptoms of thrush and is highly uncomfortable - never had this on the pill, it’s effecting my sex life as it’s uncomfortable and has lowered my libido also. - The mood swings are insane with the first shot, I was very emotional and distressed, increased intrusive thoughts about my relationship, didn’t like my body etc. - I’ve always had clear skin until the injection I noticed the odd one or two almost cystic types spots which were painful and rather embarrassing that would last for weeks. - Noticed fluctuation of breast size too I probably dropped a size or 2 but didn’t loose any body weight. Not sure how long it’s going to take to go back to normal but definitely advise to anyone wanting to go on it, research research research and book a session with your gp to review it.

Great at first, completely stopped my periods however I noticed I was feeling anxious and low. My sex drive also completely disappeared.

I feel scared for not seeing my period and the acne is really worrisome expecially when i never had acne before.
