Apparently, the hormone oxytocin that causes you to have contractions is very similar to the hormone that signals your kidneys to hold water when you get a bit dehydrated (I can't remember the hormone name). These two hormones are almost identical - they only have one molecule that is different. As a result, pregnant women's bodies will mistake the dehydration hormone for oxytocin starting contractions. That's why if pregnant women just get a little dehydrated, they can have contractions. So my doctor told me the next time that happens, drink a whole bunch of water and wait to see if they stop.
Oh, I love chemistry!
And don't worry, I've been resting more and downing the water. I'm feeling much better today!
