I had a lot of side cramping with ds1... OB said it was ligaments stretching.
I have had lots of cramping today, but I think I overdid it. We have been away a lot lately and our garden was a mess, so dh, the kids, and I went out to do some weeding for about 1.5 hours... it was hot, yucky, and hard work because it had gotten so bad. After that, I had some pretty bad abdominal cramps, I don't know why that would've happened unless I was pg??? Never has occured before, but I guess stranger things have happened.
