Add me to the list. Can be quite severe, lasts anything from 3-8 hours, and is usually on the one side. I have right-handed ovaries. The left one is lazy and can only be bothered doing its thing maybe once or twice a year. Religiously 14 days before my period starts, down to the hour - makes AF prediction incredibly easy.

Something else I've quite enjoyed hardly having any of in the last couple of years. Too much being pregnant and breastfeeding.
