Severe morning sickness:
Your body needs to produce double the hormones hence be prepared for increased nausea and vomiting. This is because the body is producing more hormones to support the growth and development of two babies, which can lead to a greater level of morning sickness. If you get a condition called hyperemesis gravidarum, a brief hospitalization may be needed.
More mood swings:
Again, given more hormones, you may experience cranky moods more often.
Foetal movement in more than one area:
As the babies grow, they move around and kicks can be felt in more than one area of the belly in the second trimester.
More weight gain:
You will have the weight of two babies, and if fraternal twins, two placentas and sacs.
Feeling more tired:
Twin pregnancies can cause more fatigue and exhaustion, as the body is working harder to support two growing babies, which can lead to a greater level of fatigue and exhaustion.
More prescribed vitamins:
Your doctor might give you more supplements than those given in a singleton pregnancy.
Very Frequent Urination:
Frequent urination is a common symptom of pregnancy, but it can be more pronounced in twin pregnancies. This is due to the pressure of two growing babies on the bladder and urinary tract.
Rapidly growing uterus:
A twin pregnancy can cause the uterus to grow more rapidly than in a single pregnancy. Belly appears larger than expected for the gestational age and is one of the early signs of twin pregnancy.
Twin pregnancies require more calories, which can lead to an increased appetite.
As expected, the belly will appear bigger than that of another woman at the same week of pregnancy who is carrying a single foetus.
The size of the belly can also depend on the position of the twins in the uterus. If the twins are sharing a placenta and are in a single amniotic sac, the belly may not appear much larger than a singleton pregnancy. However, if the twins are in separate amniotic sacs, the belly may be larger and have a more pronounced shape, as the babies are likely to take up more space in the uterus.
Based on your unique case, you might need more doctor visits and more scans.
Chances of delivering early:
A twin pregnancy of 32 weeks is often considered the same at a singleton pregnancy of 40 weeks.
