I have this pain in my lower left side of my belly. I have done some research on line that says it's most likely round ligiment pain. I can't hardly walk at times and I have been in tears from just adjusting my sitting position. This is my second pregnancy but I don't remember having this type of pain with my daughter (6 yrs). I had other issues with her, Preterm labor for example. Should I be concerned or is this natural??
