Your schedule may be off becuase of the m/c, but I have read from women on here who have gotten pregnant before they get their period after a m/c, because you would ovulate first.
Well my dr told me that women are most fertile the first 2 weeks after a m/c. I had a m/c in sept and the next month I found out I was pg so yes you can! My cycle has always been regular since I was 11 so the only time I had an issue was with one of my m/cs. Best wishes to you and take care!
I agree with ArmyPrincess, I got pregnant after my first miscarriage with 2 weeks becaue of our little ooppy. Unfotunatly that let to a miscarriage as well but I highly doubt it was becasue of the first.
