Period after MC

Erin

Had a mc at 5 weeks and my HCG levels was down to normal within days. My Dr said I can start trying right away since it was so early. I took an ovulation test and told me I ovulated now I am on day 35 of my cycle 7 days passed a missed period a no positive pregnancy and no period. I'm so confused since it said I ovulated and if I'm not pregnant why hasnt my period started??
