I need some advice ladies

Emily
I have been on the depo shot for 5 years. Took my last shot September 5, 2014. Haven't started a period again yet. I believe I just went through a chemical pregnancy because I was having all the symptoms and faint positives on hpt. Got blood work done and it came back negative. So i need some advice, what can I do to jump start my periods and get back on track.
