Cramping and lower back with Depo Shot is it normal?

[Mommycotton2119]

Hello ladies,

I've been on the Drop shot since October of 2016. I will be having my 4th shot next monday. For the most part it's been working up till now. I started my period on June 1st. It's light not heavy like my periods used to be before the shot. I've dealt with ovarian cyst and I have endometriosis has well. I had surgery in 2013 to remove a very large cyst on my right ovary and my doctor at the time had to take my ovary and tube because they were heavily damaged. Well this month with my period I'm having cramping and pain in my lower left side and my lower back. Has anyone experience this with the shot and going on their 4th shot. I hear it can take some women up to a year for the shot to work. Any advice is very appreciated. Thank you
