tightening of stomach pain

Chelsea
Does anyone get round ligament pain in first trimester? I'm not sure what it is but I looked up the pain I was having the other night and it sounds like round ligament pain. I was so scared that something wrong with my baby.
This makes me wicked nervous I haven't had a first doctors appointment yet should I go to er. This my second kid,I had no problems with my first. I'm about 8 weeks.
