Hello, third trimester!
Your doctor will have sent you for some blood tests early in your pregnancy. One thing blood tests measure is the Rh factor, a substance found in the red blood cells of most people.
If you don't have it (if you’re Rh negative) but your baby does (is Rh positive), there is potential for your baby to have health problems, such as jaundice and anaemia. Your doctor can prevent these problems by giving you a vaccine called Rh immune globulin at 28 weeks and again after delivery.

Eggplant!
At over 2 pounds and measuring 15-16 inches long your baby is growing at a great rate now. She has also developed some new skills such as blinking, sucking, couching and practising breathing. She will be starting to dream now too, so now would be a lovely time to read them a bedtime story.
Pregnancy symptoms at 28 weeks
Trouble sleeping, aches and pains, shortness of breath, leaky boobs and Braxton Hicks contractions.
