I am about 13 weeks pregnant. I picked up my 33 pound 2 1/2 year old last night to take her to bed. As soon as I stood up with her, I felt a sharp pain in my lower right abdomen . Ever since then, I have been having pain in the same spot. The pain is not constant - it just happens whenever I move a certain way, cough , or even take a very deep breath. Could I just have strained a muscle or the round ligament , or could this be a sign of a more serious problem?
