Cramping at 11weeks

Hi ladies, since turning 11 weeks my once in a while cramps have turned into a daily thing...maybe 5 times a day. Today we were shopping and my husband startled me and it made my stomach muscles flip. When I got home I was a little wet down there but it looked clear on my underwear. It's dry now and there like a 1 centimeter brown stain...like there might've been some blood with it. Do you think this is ok? I planned on calling my doc tomorrow but I wanted to see if anyone has had this happen to them!
