Peak for 3 days?

Hi ladies! This is my first month tracking my ovulation. I got my peak with a Clear Blue digital advaced (solid smiley) and a cheapie on the 2nd. I was having horrible ovulation pains on the left. On the 3ed it was the same thing, pains (less so) and still showing peak fertility. On the 4th however, once again showing peak fertility but the ovulation pain was on the right.

On the cheapie the test red line showed up instantaneously all three times. I started testing on CD 1 so I do know the difference between a positive and negative lol

Could I have ovulated from both ovaries a day apart from one another?
