I had regular menstruation cycle until first depo in February 2013. I bled a little in March, April, and May. Nothing in June, July, or August. I did follow up with five home pregnancy tests, experiencing pregnancy symptons. Went to ER 8/14/2013 and they said I was NOT pregnant and that my hormones are unbalanced, or, thyroids. I've gained almost 32 pounds in 6 months. What do you think the problem could be?

The problem is the depo shot. It is notorious for weight gain and missed periods.
