Babies

The babies will double their weight during this period and by week 28 each baby will weight around 3 pounds and will be about 35cm long.  The twins will cross the threshold of viability, meaning that due to the remarkable advances in care for premature babies, their rate of survival increases considerably.  If born now, there is a 90% chance of survival with medical intervention.  Their facial features are becoming more distinct and their eyelids will become unfused.  You can even sometimes see one or both babies opening and closing their eyes on ultrasound.  Each baby has their own sleep cycles and will begin to respond to sound during this month.

Mum

Your uterus continues to grow and stretch as the babies increase in size.  This can cause ligament pain and general pain in the uterus as well as frequent urination.  Edema (fluid in your body tissue) can be causing swollen extremeties.  By now you will be feeling very heavy and exhausted and the weight of the pregnancy is probably starting to affect your back and legs.   As the babies move down into your pelvis, you will experience pelvic pressure and increased pressure in your rectum.  You should still be feeling movements from the babies every day although the movements may feel different to before as they do not have as much room to move around now. Because you are carrying twins you are likely to experience a lot of Braxton Hicks contractions.  These are contractions of the uterus which feel a bit like period cramps and will make your belly feel hard.  These are unlikely to be painful but can be uncomfortable and unlike true labour contractions, there is no pattern to Braxton Hicks contractions.
