I am 18 weeks 3 days pregnant. I have recently niticed while sleeping that when i turn to roll over onto my sides that i am getting a kind of stabbing pain under the right side of my ribs. This only happens while i am on my back rolling onto one of my sides. As soon as i am turned over, the pain seems to stop. I am not sure what it could be and why it is happening. is thins something normal? I have also heard that it is a bad sign if I feel any type of cramping in my lower abdominal area, along the same line as menstral cramping. I sometimes feel those cramps too. Is this something to be worried about. At my appointments the doctor says that the baby's heart beat is great and he is always moving around on the monitor, even though I cant yet feel him. But these pains are something that are scaring me. This is my first pregnancy and I have no idea what to expect.
