Could I have already ovulated? This is the first time taking any opks. Ive been out of town since yesterday night and I wasnt with my fiance so no baby dancing happened. Ive been in my fertile window since Wednesday, when I left. And when I got home I immediately took the one on the top. It was pretty dark so I figured I would be ovulating soon since tomorrow should be my most fertile day. So I took the bottom 2 today. The top 2 are off brands, and the bottom is a first response opk. Since the top is darker, is it possible I already ovulated? I felt some pain on my right side around 12:30 yesterday and I left to go hone at 6:30. Im just curious if you think I already ovulated?
