Mine stopped for about 3 months after my surgery. I am not sure I would want medications to start it back up if everything was checking out OK otherwise. Basically, it just means that your body does not think you should be getting pregnant right now. But, if it worries you, I guess hormones to stimulate menses would be OK. But, for me, I didn't miss it, and since I was anemic, I could use the iron I would lose from my period.
