The period covering 27-40 weeks of your pregnancy is the third trimester.
Most of the earlier pregnancy symptoms in the first trimester would have returned by now. Sleeplessness, frequent urination, shortness of breath, heartburn or fatigue can again start bothering you. Understand your body and take all the needed care.
You will be indeed putting more weight by the third trimester. It is quite common, as you are carrying two fetuses. This weight gain is relatively necessary to cope up with the labor and birth.

In your early third trimester, you might encounter continuous movements during different parts of the day. This might be because one or the other fetus keeps moving. Soon many moms can very well differentiate which fetus is moving based on the position and time of the kicks.
But these movements tend to slow down when you are nearing the end of this trimester. The space in the womb is almost occupied, which in turn slows down the fetuses from moving freely. If in case you are under medical supervision (in your later stages of pregnancy), you can even tell your caretaker where they can find your little dudes heartbeat, during their routine checkups. You will be more familiar with their positions by now.
Once you reach the mid of third trimester, the growth rate of your fetuses will be slowed down compared to singleton fetus. This is mainly because there isn’t much space for two fetuses in the womb which is usually occupied by one. This is why generally the twin babies birth weight are low when compared to a single baby born in the same gestation period.
By mid of this trimester, most parts of the fetuses body would have been developed except for the lungs(which is not developed fully until 35 weeks). The fetuses will be gaining bone mass, fat and develop muscles which will help them to regulate their body temperature once they are born.
The fully opened eyes with eyebrows and lashes will soon be responding to light.
The fetuses will be practicing the routine of swallowing, digesting and excreting. The bones will continue to grow stronger. All the grown organs will be matured and fat will be accumulated thereby getting ready for birth.
You should be very careful in the third trimester as there is a chance of preterm labor. Any abnormalities which you note like increased vaginal discharge, leaking amniotic fluid or pressure in the pelvis should never be taken easily. Reach to your medical practitioner immediately and seek the necessary advice.
And your delightful journey has thus come to an end! Two pairs of eyes would be looking lovingly at you by now!
Happy twin parenting!!
