I had a scary experience tonight. All of a sudden I had this awful pain in my whole stomach. At first I thought I had to use the bathroom but I haven't been able to "go". Then I thought it could be Braxton hicks but I'm only 11 weeks. It was so intense and hurt so badly. It didn't last longer than 3 to 5 minutes but I was so scared after. There was no bleeding and hasn't happened since but this is my first baby so I don't really know what to expect.
