I got off the depo Jan 24th after one shot. My doctor said it would take about 3 months for it to get out of my system. I’ve been bleeding but not full on period bleeding just here and there spotting for 2 weeks.. is it normal for me to be bleeding at all this early after getting off? And if so why is it not a period?
