Missed misscariage end of june 2018

I got my first period after a d&c on the 29th of july to the 2 of august. I'm about 12 days late for my period. It's is normal for my period to be irregular after the first period I'm just confused as I haven't had any signs of being pregnant at all so I don't think that's the case I've been having quite abit of watery discharge sorry to much information. Has anyone had a missed miscariage and had a d&c? How long did it take you to fall pregnant again? And when did your cycles regulate?
