Girls, we're at week 36, after the PA I fell asleep and woke up three hours later with very sharp pain in my stomach. The pain is dull, pulling, straight clear that it presses on the perineum. My legs hurt too. Could these be contractions? The PA was normal, I didn't feel any pain, it passed as always. But my lower abdomen hurts.
