2. Your baby is positioned lower

Once you have a first pregnancy, your uterus never shrinks back to its previous size. As a result, your belly starts growing faster and even shows faster than the first time, making you look bigger sooner than before(1).

  • Pregnancy stretches the muscles of your abdomen, making them weak2.As a result, your abdomen is not able to support your baby well the second time, which causes your fetus to move lower into the abdomen. You may feel it is not a good thing, but if your baby is placed lower, it will mean that you will have lessdifficulty in breathingand eating, as compared to your first time.
  • However, the problem that you may encounter when your baby is placed lower in your abdomen is the urge to urinate more frequently than last time. You will also experience a higher pressure on your pelvic area and your bladder, which can result in a lot of pelvic discomfort. Carrying your baby lower in the abdomen can also place more strain on your back, resulting in back pain that can sometimes become a permanent fixture.
