In regular oeriod after miscarriage help?

Lindsey
I had a miscarriage april 20th. I did not get a period until the end of june and in july i started on time. However that period lasted 21 days. I went to see the doctor and he told me sometimes that is your bodies way of regulating back to normal and that everything looked fine. I started july 26th and it ended aug 15th. It is now September 14th and i still have yet to have my period. The doctor did tell me that another reason for the long period was due to not ovulating that month and that after my period ended i most likely ovulated within that week. I am just wondering if anyine has experienced this. I know, i know i can take a test to see. But i honestly just dont want a let down if it says negative. :/ so just wondering if anyine else has went through this or has any advice? Thanks in advance
