TTC after 2 miscarriages

I had a complete molar pregnancy in Feb last year. Had to stop trying for 6 months as the dr suggested...Started trying again in Sep. and got pregnant in Nov...but miscarried in Dec...Since then I haven't had a normal period yet...last 2 cycles had been really light....Anyone on the same boat? How long does it take for your cycles to normalize after miscarriage? We are trying for our first and haven't had any positive experience yet.... :(
