Everyone is different. I was on depo after my first and I was the lucky 1% that was on my period almost constantly while on depo. I ended up conceiving while on depo!! If she's been off for that long, then maybe it's time to get checked out. It may also not even be an issue with her, it could be a low sperm count on her partners part. I'm not a doctor, but I know that the more you stress about it, the harder it will be to conceive. Good luck! :d

In a surge of luck when I talked to her yesterday after writing this post I found out that she had taken a pregnacy test and it came pack positive.

How wonderful!!! Good for her!! I on the other hand have made a doctor appt since I have no clue what my body is doing!! I think i'm pregnant but my test are coming back negative and my period is not normal at all. There's no blood! Lord help me!!

Glad to her she has the result she wants.
Here is what schering have to say about contraceptive injections

"periods often become irregular or stop, and some women gain weight. Regular periods and fertility make take a year or so to return after stopping the injections, so this method is only suitable if you want long term cantraception."

Has she talked to her doctor about it?

congratulations!
