OVULATION AFTER D&C?!

I had a miscarriage and d&c in early December. Before this, I ovulated every cycle on cd17/18. I’ve been tracking my ovulation early, since this is the first cycle we’re trying after my period and i tested this morning at cd12 I just got a flashing smiley on the digital. Is this accurate? My premom test seems a little darker than the ones previously, but definitely not positive. Is it possible that after my d&c, my body is ovulating on the “normal” cd14? Has this happened to anyone?
