Yep I did - it was quite noticable on the day I should have got my AF, and for a few days after. I don't normally get bad period cramps, but I thought this was pretty much like them - a bit worse maybe? I also had a small amount of brown spotting.

I also had some pain on my left side which turned out to be the corpus luteum on my left ovary - apparantly fairly normal thing that can happen.
