Hi, I've been off the depo shot for over 4 months now, I haven't had a 'normal period' since dec 2010! I conceived my son in feb 2011 without a period. He's nearly 2 years old now. I had my last injection in jan 2013, so the effectiveness should have worn off around April. My periods have always been irractic & vary from 13 day cycles to 1 a year! My question is - around nearly a week ago I had a random 2 days brownish/red discharge. I thought it was my body just waking up again after the depo but after the 2 days it stopped. From then on I have had a white stringy discharge constantly in my undies. I have had headaches & lower back pain, cramps & milky discharge from my breast (I've had the discharge a while) so could I be pregnant? I haven't done a test because I assume the depo would take forever to leave my system!? Me & my husband would love another bundle of joy so any advice would be greatly appreciated :) thanks Suzie x
