My periods have been all over the place. Of course, I'm pretty sure I'm perimenopausal now, so my experience probably isn't a good example for you. I've had periods close together, spotting, no period for six months, lots of clotting...you name it!
I would have to say that most of the post-op women on this forum report their periods are a little more troublesome, probably due to the release of estrogen during weight loss. However, the positive results we see from surgery are worth way more than yucky periods.
