I have been on the depo shot for about 5 years now. Never had any side effects and I stopped having periods completely after my second shot. I just received my shot again last week. I got it on the last day of my due date. Today I woke up with some slight period cramping and light bleeding. Not spotting but not a heavy, steady flow either. It has lasted all day. Should I be concerned? This is definitely not normal for me and ive gotten my shot close to the over due date before and never had an issue. Im a little stressed out and with the holiday my Dr., OBGYN & Planned Parenthood are all closed.
