Tad confused about date...

Based on my chart and my +opk yesterday at CD30, when did I ovulate? Yesterday or today? Because my temp dropped two days ago to it's lowest point and now it's going up. So when did I ovulate? I'm hoping me and DH made it since he picked a fight last night cuz he was cranky we didn't BD so I'm hoping if I ovulated two days ago and we BD on Monday, that we made it and if I O yesterday I hope we haven't missed it :/​
