Depo is fantastic as contraception but if you will be planning more kids, don't do it. It can make TTC a very long difficult process and really mess your cycles up. I know everyone has heard the horror stories of its long term effects but I hadn't until I went off it, we started TTC and got stuck with 14 day cycles for months. Some people end up with them for 12months plus. Just feel I needed to spread the word incase your like me and didn't know.
