Round ligament is a sharp pain below your belly either on the left or the right side but you shouldn't feel any tightness unless you're talking about braxton hicks then yes. Starts at 2nd trimester to 3rd. Comes and goes for a few seconds and will normally go away when you change your position. It shouldn't be painful at all but just uncomfortable. This is how your uterus contracts and your body is preparing for birth later on.
