Im 5 weeks pregnant and am having a pick on the left side, comes and goes with position change and going to the rest room, could it be something serious?

See your doctor: Pregnancy comes with hormone changes that cause constipation, bloating and discomfort. Some cramping is common. If pain in the right or left occurs we think of an ectopic pregnancy (outside the uterus). This is very dangerous. We usually check your pregnancy hormone levels then to make sure they duplicate in 2-3 days. You may just have some GI issues but get it checked out.
