Ovulation symptoms??

Hi ladies, I’m on cycle day 16, currently having cramps, leg pains, and lower back pain. Could these be ovulation symptoms? I didn’t track when we conceived my baby girl, so I don’t remember what I felt then. I’m more in tune with my body this month since we’re trying which is why I’m noticing this. Do you ovulate after these symptoms? During? I only use the opk’s once a day since I don’t really have time in the mornings or mid day at work and they’ve been negative. I had very light ewcm yesterday and it was heavier today, but still not much. I’d greatly appreciate it if you could share your symptoms.

Thank you!
