Ovulation pain

Yeowch!
​I don't know if I'm just noticing it way more off of BC but def have left sided ovulation pain today/tonight. Never noticed as much on BC or when not TTC. Hubby and I BD but curious as to when you guys think the best time is? 
​Does the pain signal go time or in a few days most fertile? Glow has me starting fertile week today.
