So Fu$&ed Up!

I thought I had ovulated on CD11 (increased sex drive, O cramps and the positive opk). After those symptoms continued I kept testing and on CD16 I got a positive opk again! And THEN, on CD19 the most positive opk. During that whole time all the symptoms were there. I know a lot of people will say I was trying to ovulate and couldn't but are there any other theories? This makes getting pregnant so much harder!
