Are sharp lower abdomen pain normal during 9 weeks pregnancy? what are its possible causes and when does it go away? thanks

Early Pregnancy pain: It's common to have pain early in pregnancy. Typically this pain is due to ligament stretching and growing of the uterus. Unless accompanied by bleeding and cramping, this pain is typically normal. One would want to make sure that you don't have a urinary tract infection, appendicitis, or gastrointestinal problems. Sharp lower abdominal pain in pregnancy can come and go throughout the pregnanc.
