This morning I woke up with a sharp cramp like feeling on my left side. I am 18w4d. The pain is better when I'm relaxing, but does cause some discomfort when walking, cleaning etc. It sort of feels like a swimmers cramp (when you go swimming right after you eat) should I be worried or could this just be round ligament pain? I also should mention that I was very upset yesterday and cried pretty much all day.
