At my 6 week appointment I got the Depo shot for BC, I had one period but didnt track it. My boyfriend and I have had unprotected sex since then, my doctor didnt give me any directions except to come back in 3 months. So a friend had said about how she quit her shot over a year ago and still hasnt go her period back, so i started doing some online searching and it had said to use protection any where from a week to a month so I need to know what exactly the time frame should have been. I'd love another child even if he or she wasnt unexpected.
