Chart Help

This is the first chart I have ever done and started in middle of 53 days cycle following my miscarriage. I still haven't started cd #1. As you know last week I went to the doctor and had a 26mm follicle with E2 levels only in the 40's. I assumed it was a cyst. Now looking at my chart it seems I did ovulate. Any help on this would be great.....

Do you believe ovulation took place? Then the second dip I thought was me getting ready to start my period finally and then temps when back up. LIke I said I don't understand charting yet.
