TTC 35 day cycle

Briana
I have been tracking my cycles since I took out my iud on May 18 I had my period the following day and it lasted 4 days the second month I had my period on June 19-22 and then again on July 19-22 (which I thought was odd) and August on the 22-25 now it's September 29th and still no period. The August period I assume was a few days late due to I started working out a lot more but I still haven't gotten my September period... I have had some pregnancy symptoms heightened smell, tiredness, extremely hungry all the time and sore breast but I have taken 2 test and both said not pregnant idk what to do except wait.
