Welcome to the start of the third and final trimester of pregnancy. The changes happening to you and baby will be radical from now until delivery. Mood swings, sudden food cravings become intense as the third trimester pregnancy begins. Dads and others who are in close contact with you might start feel as miserable as you do. So just try to be soft on them and manage your mood swings. You can do this by changing environments (going out for a walk) or jotting down your emotions on a piece of paper. Calling friends and chatting with them will also help you chill out.
Weight gain will 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 is a very slim chance of any serious complication moving forward. The baby is about 15 inches in length and now weighs about 2 pounds. The skin, though wrinkled, is adding on the required fat layer as the pregnancy progresses smoothly.
