Unless you want to end up on 15 kids and counting or you're a bit of a minx living on the wild side you're going to want to be on some sort of contraception. I've tried my fair share. The implant, the pill (more than one type) and currently on the injection which I have been using for a year. However, once my 3 months are up I will be coming off and trying something new. I've had bad side effects with all three but I'll explain why I personally feel like the injection is the worst one so far.
