Growing Pains?

For the past few days I've had some cramping. At first it wasn't too worrisome. But yesterday I started to get concerned. I know most of the time things are "nothing" and go away on their own. But what if it was the one time when "nothing" was actually "something" and I ignored it? So I called the doc. They advised me to put my feet up, rest, and drink lots of water. If it got worse or if the cramping was accompanied by bleeding, I should come into the office. It did not get worse and I have not had any bleeding so I guess things are ok. But the nagging cramping is still there even today. I guess it's just growing pains. Because my belly sure is growing!
