Re: How do I get my period back without using a birth control pill?
I would assume that if your periods were regular before you went on the Depo Provera, they should eventually get back to normal after your body has adjusted after you get off of it.
Sometimes the body needs time in order to readjust. If you are concerned about the estrogen in the pill, you can always get off the Depo and go on a progesterone only pill for a little while until your periods are regulated. Then you can go off it and hopefully the regular cycles will continue.
Otherwise, I would just go off the Depo and let the body adjust naturally. It may take some time though so you may have to be patient and be watched by a physician for a while until things get back to normal.
Of course, eating a healthy diet, regular moderate exercise, keeping to a healthy weight and proper sleep (7-8 hours a night) will most definitely help your menstrual cycle to get back to normal.
If all of this does not work, then I would have some things like hormones and your thyroid checked out. This is to make sure that your irregularity is not caused by something else. However, most likely it is the shot and you need to allow your body to take over total hormone control again.
All the best.
