I'm 8 weeks pregnant and I just woke up out of bed with shooting pains... kind of Similair to gas pains.. I have not pooped in 3-4 days... the shooting pains won't stop. It happens like every 5 min and the pains last for 2 min. I'm legit crying t hurts so bad. I looked on google and says round ligament pain is possible.... should I go to the ER?? Help
