I had my first depo injection November 2017 and had my last one January 2019 and have not been on any other contraceptive since. Since coming off the injection I had my first normal period 13th July, I was on for 1 week which is normal for me. After this i had slight bleeding for 4 days starting the 28th July. My usual cycle length is 28 days which means I am overdue my period no matter which 'period' I count the 28 days from. Did a pregnancy test monday 26th Aug it was negative but I have been extremely tired over the past week, and really hungry. No sign of period yet, is there a chance i could be pregnant or is this just my body trying to get back to normal after the depo injection?
