After coming off the depo shot it took 6months for my cycle to come on..when it came on March 2013 it stayed on for a while.. IN April i did not recieve a cycle.. i took a test April 24 and i was negative..since April i have been having alot of symptoms of early pregnancy. Excessive saliva, back pain, gassy, constipated and nauseated. I don't know if i am pregnant i know my body has been weird but idk..
Maybe it's time for a doctors appointment where they will investigate if you are pregnant further with their urine and a blood test to confirm or deny.
Coming off the depo is pretty hard on the body, I didn't have a period for over a year when I came off it.
Hope this helps
