Depo shot

So I've been researching this topic for awhile now but I have been so nervous about starting birthday control but after my last period I knew I had to do something so I saw the NP at my family doctor today (she's really cool my doctor is a man and I felt uncomfortable asking him this) I asked and asked and asked she told me that she gets the shot and it's great! So I decided since I'm not too good at remember to take medicine at a certain time that the shot
Is the best option.  Well I have heard some horror stories about it. A few people I know that haven't gotten it had their period the entire time they were on the shot. EVERY. SINGLE. DAY! I can't do that so I'm nervous. Let me know how the shots going for you please!
