Common Bodily Changes

The body of a woman pregnant with multiples does tend to have slightly different changes as compared to a woman going through a standard pregnancy, around this stage. A bunch of changes are common, irrespective of the number of babies inside you.

  • The growth of the babies will cause the uterus to expand in size as well. This expansion depends totally on the number of babies residing inside. Even if you are only 9 weeks pregnant, the belly might start showing for a few people. The uterus also adjusts its orientation as it grows in size, which makes it tilt slightly upwards with respect to the body.
  • Frequent urination would still be present this week and will continue to trouble you for a long time. The adjustment of the orientation also puts pressure on the bladder, which causes you to constantly feel like peeing.
  • The hormone levels that fluctuate constantly can lead to headaches in women. Mothers who have had migraines earlier could find themselves facing them again. As normal as this condition might be, it certainly isn’t a comfortable one. Combined with exhaustion, stress, and anxiety, this can easily remove all the fun and happiness of being pregnant.

  • Working women whose work schedules require them to sit in front of computer screens for long durations are at risk of facing headaches and even strain on the eyes. Taking rest is the only way to counter this.
  • Weight gain continues to happen gradually, though it isn’t as much to make a huge difference. Fluctuations tend to happen around this time, causing your weight to reduce for a few days and then increase again. If the weight gain is excessive than normal, you should consult the doctor.
  • Pregnancy changes and the boosted flow of blood towards the breasts cause them to expand in size. This expansion puts pressure on the skin as well, leading it to stretch and even get itchy at times.
  • Acidity and constipation could occur, which can also be combined with a tendency to pass gas or burp quite often. There’s nothing to worry about this, except for embarrassment if you were to fart in a social situation. A proper diet and consumption can reduce the chances of this happening. If the symptoms are bothering you too much, have a talk with your doctor.
  • The completion of 9 weeks marks the strongest phases of nausea and morning sickness in a woman. Most women begin to hate their pregnancy around this time, and the irritation can get absolutely frustrating at times. On the brighter side, these symptoms will start reducing in the coming weeks.
