TTC #1

Hello!
​My husband and I are beginning to try to conceive baby #1. I am having trouble figuring out when I actually ovulate though. All my OPKs have been negative, and my CM is very light, if any at all. I've had what I think is ovulation pain for the past couple days. Really bad on Sunday, and it's been a dull pain ever since.  According to the calendars I'm using, this week is the week it is supposed to happen I just can't figure out when. Should I just baby dance every day? I need help!
