10/14 cycle buddy? +ovulation question

Kari
Third month trying to convince. I had a miscarriage in February and we are praying to be blessed with our rainbow baby!
I'm confused when I ovulated this month. Or anytime for that matter! My period was 9/15-18 and my cycles are 29 days long on average. Normal periods every month. I took ovulation tests 9/27-10/3 and they were all negative? I can't figure out when I ovulate. Could it be right after I got off of my period? Please help. :-(
