SUPER FED UP

Im 19 and got my first depo shot about a month ago. My period came 2 weeks early and hasn't left since. I'm now coming up on my 3rd week and still bleeding. This period is making me feel so ill and tired. What on earth can I do to help it or get it to end? What have you girls tried that's worked or not worked? Please no comments about sucking it up. I've never been on birth control before and my gyno isn't very great at preparing or being honest when it comes to questions. I seriously need tips.
