Birth control shot and spotting

Started the shot as an easy way to get on BC. Didn't have to get another shot for another 3 months; however, it was the worst decision I made. I had spotting and sometimes even heavy bleeding for 18 consecutive days straight. Gained weight as well for the following 3 months.

My skin is brighter, my hair is healthier. I’m losing weight, I went from 127 to 116 in the 3 months I’ve had it. I went from having no sex drive to being turned on all of the time. My only complaint is that even though I’m always turned on, it’s still a little difficult to get wet, and I experience alot of weird discharges

The beginning i bled a lot, 40 plus day periods with few breaks in between. After about a year my periods went away and I only have spotting now. I recently found out I should only be using this form for no more than 2 years but this is my best option. It has been affecting my bones because I experience pain in my knees and hips that I haven't before this birth control. It does control my acne and is reliable which is a plus for me, i haven't experienced weight gain which is a common side effect. I have migraines more often after my shot and leading up to it as well. Overall I don't care for birth control in general and will be looking for other options.
