I was on depo for 10 years. I didn’t get my shot and then I had two periods and got pregnant so it happened pretty quick. I’d say a couple weeks after you don’t get it , you will start to spot and then when you get your period , you know it’ll be completely out your system then
I was on it for about 5 years got off and got pregnant the following month I was shocked bc drs told me it can take 6 months to get it out of my system
I took it when I was younger, years before I TTC. I would highly recommend the next time you look for birth control, you choose another. It’s the worst one for our bones
