3rd cycle after mc!!

Amanda
After two years of trying I  was pregnant but sadly had a mc on July 4th. My period came back exactally one month later. My 2nd cycle was 36 days (my usual cycle is 28 days). I'm now on day 38 of my 3rd cycle. I can't help but wonder if this could be the month. How much longer should I wait before testing!? I don't want to be dissapointed.
