At 20 weeks, is it normal to feel very light movements, only every few hours, and not notice movements if you're doing other things or wearing a pelvic support belt?
I am increasingly scared because this baby has a straight (uncoiled) umbilical cord, which can, in theory, compress or kink very easily, leading to hypoxic brain injury. Periods of non-movement are probably fine but I just don't know how often is often enough for movement...
