Opk lines. People with experience ??

Lauren • 31, partner is 35. We have three children, William 10, Georgia 2 & Eliza just born. I work with domestic abuse victims in the north east of England. Partner is a roofer/joiner.
Today is cycle day 18 for me. I usually have a 29 day cycle. Bang on time. However my last cycle was 32 days. Little sod. Anyway, ovia and glow are not on parr with each other. My ovia says fertile days are 16th to 21st. My glow says fertile days from 14th to 22nd! So.. These are my opks. From last Saturday to this morning. Have i ovulated?? I no line needs to be as dark or darker than control line. But this is all I've got......
