ovulation at the very end of period

I'm on the sixth day of my cycle and I have egg white blood tinged cm. It was completely creamy and tacky up until now. Have any of you ovulated this early in your cycle before? I know it's usually day 14 with a 28day cycle but I had a D&C (my hcg has been back to zero for a month now) so I'm wondering if that threw off my cycle
