I've generally always had really strong ovulation pain. When I was in high school I actually started on the contraceptive pill because the ovulation pain was so bad each month that I would be double over at school.

When I fell pregnant with DS it was definitely an egg from the left hand side.

Since having babies though the ovulation pain seems to be much much less. We don't know what side DD came from because she was IVF, but I'm now pregnant with a VERY surprise baby and never knew I had ovulated. It's been at least 16 months since my last AF and looks like there won't be one for quite some time to come, lol.
