Braxton hicks..

I am 9 weeks and 2 days, this is my second, and at work yesterday my stomach started getting hard and tight, it was so uncomfortable, I thought I was going crazy! I didn't know you could have them so early. I googled it and apparently we have them early most people just don't realize their having them. And with a second, third etc pregnant you notice things sooner. Anyone else had these early?!
