At twenty seventh week of pregnancy, the changes would be radical from now on. Mood swings, sudden food cravings and the not so real labor pains are all a reality as the third trimester pregnancy begins. Dads and others, who are in close contact with you, might feel as miserable as you do. So just try to be soft on them and manage your mood swings and cravings by changing environments like going out for a walk or jotting down the emotions on a piece of paper or calling friends and chatting with them or indulging in any other activity that you feel would help chill out.
Weight gain as mentioned earlier would be quite drastic from now on. However, this is very much required and is completely healthy. Therefore do not panic and most importantly do not plan out a diet schedule. The weight gain is desperately required for your and the baby's health. There could be minor breathing issues due to the shortage of space required by the lungs to expand. Simply ignore it and think about your baby.
The baby is progressing well. And if she's made it through the stages of pregnancy and has reached this stage without problems, there are very minor chances of any serious complication. About 15 inches in length, she now weighs about 2 pounds. The skin though wrinkled, is adding on the required fat layer as the week by week pregnancy progresses smoothly.
