3. Pregnancy Gingivitis:

Since your body has doubled the blood circulation now, swollen and tender gums may be a common experience during pregnancy. It can also soften the gums and cause minor irritation while you are flossing or brushing your teeth. To overcome the situation you are put in right now, the best thing to do is limit the speed at which you brush. This will avoid careless cuts. Since otherwise, not only will these cuts lead to infection, but the bacteria forming might also go down with your food to your stomach.

4. Weight Gain:

Weight gain is very normal during pregnancy. By the 13th week, you should be aiming to gain 25 to 30 pounds and this is the recommended weight gain. Switch over to healthy foods to overcome the excess weight gain, however, exercising will add more benefits on your list.

5. Shortness of Breath

Shortness of breath happens throughout your pregnancy. In the first trimester, the high level of progesterone can make your breathing really difficult as the body is adjusting to the new hormones. This is usual. One way to avoid this is to actually give your lungs a lot of space for breathing. Sit up straight and sleep on high levels so that it can expand the space in your abdominal area.

Fetal Development of the Baby:

  • Your baby is now 3 inches long and weight is about 0.8 ounces and looks like a miniature human baby. The head at this point will be big and the rest of the body will catch up with time.
  • By the 13 weeks of pregnancy, your little baby’s legs and arms are growing. The muscle control of your baby is also improving. Even though your baby has very little control over his or her muscles now, he or she is probably flipping, kicking and flopping by now.
  • His/her toes are now separate and are about the same length. The baby’s ankles would have also taken shape and are mature.
  • You will notice that the amniotic fluid level would have risen by now and this means the baby now has a lot of space to move inside. The level rises up to 25ml. This amniotic fluid will increase in these weeks of pregnancy but then in your last few weeks of pregnancy, the fluid will gradually decrease.
  • At this point, you will also be able to see the bones of the baby, even though the skin has developed. The skin will be transparent, thus giving you a view. This is also the week, where the baby will gain some pounds and make his/her bones stronger.
  • This period will have the left and the right cerebral hemispheres of the baby connecting. Since each hemisphere controls the opposite side of the body, with the development of the brain, your baby will begin to have more control over his or her body. The motor fibres present in its brain will develop first, followed by the sensory nerves. The brain takes about ten weeks to develop completely.
