Need advice

Julie
I usually ovulate around day 20 well I used clear blue OPKs from day 12-25 never got anything so I stopped using them. I assumed I missed my ovulation or I didn't ovulate this month. Well this morning I decided to take one and I got a positive! I'm hoping to BD tonight. Do you think my odds are still good? I hope today is the 1st positive day since I didn't test yesterday!! I use the one where it gives you the 2 best days to BD.I'm having sharp pains  in my right side. Does that mean I'm actually ovulating right now?
