Baby number 3 this cycle

I believe that I ovulated on the 13th instead of the 15th glow estimated the 15th I know it’s an estimation but will this mean baby number three wasn’t trying but wasn’t not trying but I want to try something I want to see how well I really know my body and how well I guessed/calculated my ovulation I’m not going to stress or take multiple test I’m simple just going to wait until my period comes or doesn’t so based off my calculations I’m currently 2 DPO🤗
