I'm 23, 6months
pregnant now with my first baby. We did a 3d scan today in which the doctor said umbilical cord is thin. And also she asked me not to do long travel, bike travel, walking or exercises as may it lead to damage the umbilical cord. Is this really a problem to be worried? Do I have to stop doing walking and exercises? (Note : baby weight, heartbeat, hmg and other Anatoly reports were normal)
