If you were my patient, I would advise you that it is common to have irregular periods after using Depo Provera. If the pregnancy test is negative, chances are pretty good that you are NOT pregnant. HOWEVER, i never hurts to repeat the test, or ask your doctor for a blood test.
I had irregular periods for 9 months after i stopped getting the depo shot.
May last period was the 1st of sept and it stop on the 5th day i have the apps to keep track of my period and it said my period should start again on the 25th and now im three day late should i worry or how long should i wait before going to the doctor or taking a pregnancy test..
