Hi Amber, I am 23 weeks pregnant and I am experiencing the same things. Pain in my lower abdomen and on the sides. You may have possibly pulled your round ligament around your uterus. As far as the lower abdomen pain, If you get any good answers please let me know. I am going through the same thing with it getting worse when I walk around or try to pick up my other son. I had a previous c-section on July 28th of last year. So I was looking for answers to the same question.View Thread
