Your Second Trimester Week-by-Week What to Expect: A Guide

After successfully battling all the morning sickness, nausea, and other pesky early pregnancy symptoms welcome to your second trimester of pregnancy. The second trimester starts with your 13th week and ends around the 27th week of pregnancy. As you have stepped in you might have realized that nausea and morning sickness have been aside and now your skin starts to feel healthier and your hair looks shiner and thicker.

On the other hand, your little bundle of joy would also be developing and making his presence felt by probably rolling in the amniotic sac. As per Dr. Elsa, a Trained Obstetrician and Gynaecologist in Dubai in the second trimester your baby starts to develop upon the foundation set in the first trimester. In general, there are a number of big milestones taking place like growing in the size similar to the head of a cauliflower from the size of a nectarine. 

Apart from this for a mom-to-be, there are several second-trimester symptoms she goes through. The most common symptoms experienced are: 

  1. Skin pigment: During pregnancy, the production of melanin (a pigment that gives color to the skin) increases resulting in darker or brown patches on the face, darker color of the nipples, and a dark line running from the pubic region to the belly button.

  2. Dizziness: Due to changes in circulation and flow of blood to the upper body and the head feeling light-headed or dizzy is the most common. If dizziness hits you try to lie down on your side and consume plenty of fluids.

  3. Stretch marks: Be it during pregnancy or post-pregnancy stretch marks are the most talked about. Just because your baby grows and your skin changes you can experience dry and itchy skin that develops stretch marks.

  4. Leg cramps: Often experienced at night, women feel low leg cramps with sharp pain. If you feel cramps try to do stretching before bed and if the symptoms are sharp pains in the calves try muscle massage or just take a warm shower.

  5. Lower back pain: Due to weight gain and uterus expansion the center of gravity and posture change resulting in putting more pressure on the back. To get relieve from the pain try exercise or stretching.
