hopefully ovulating

been off the depo now 7 months, I took a pill to kick start my periods, it worked and it went for the regular 7 days, from the 6th November to the 12th of November. I started taking ovulation tests straight away but all negative, 6 days from the last period I came on again and that lasted for 5 days, the cramps and heaviness of the bleeding was awful, especially the clots, it honestly felt like my own body having a period and that it was back! it now says I'm 6 days away from ovulation, im getting dull pains in my ride lower side and bad backache😅does anyone think the depo is out of my system? I am praying to God that I'm ovulating!! has this happened to anyone else?? please comment!❤
