- You donât have enough amniotic fluid.
- Your babyâs growth is being restricted.

Abnormal Causes Of Belly Expansion
In most cases, a belly bump during pregnancy is completely healthy. However, some pregnancy conditions can cause a rapidly swelling belly, requiring careful monitoring. If you experience any of these conditions, make sure to talk to a medical professional.
1. Large fetus
A larger-than-average fetus will likely cause a larger-than-average belly bump.
A large fetus can develop for a few reasons:
- Male fetus: Boys are born 150 grams heavier than girls, on average.
- Gestational diabetes: Maternal blood glucose levels can rise during pregnancy.
- Maternal obesity: Extra weight around the abdomen can lead to a larger bump.
Folks who have a larger baby may need additional examinations and special delivery accommodations, which need to be discussed with a health care provider as early as possible.
2. Molar pregnancy
Molar pregnancies result from problems during fertilization, leading to an abnormal placenta. In a complete molar pregnancy, the sperm has fertilized a non-viable egg, and only placental tissue develops. Because the egg wasnt viable, no fetus develops. In a partial molar pregnancy, two sperm usually fertilize one egg, and some fetal and placental tissue begins to grow. This condition is most often diagnosed in the first trimester based on symptoms like uterine enlargement and abnormal bleeding. Most molar pregnancies result in miscarriage.
4. Large ovarian tumor
5. Fast-growing benign fibroid tumors

However, in other cases, it may suggest that there is intrauterine growth restriction. Without effective treatment, this can cause mortality for the fetus and the pregnant person.

Does Fundal Height Predict The Due Date
Healthcare providers don’t use fundal height to measure your due date. Fundal height is used to track how big or small your baby is compared to their gestational age. The best way to determine your baby’s due date is to count 40 weeks from the first day of your last menstrual period. Healthcare providers often use the first-trimester ultrasound to help determine gestational age and due date.
A Lack Of Internal Space
As your uterus will expand with your baby, certain other organs of your body like the placenta and the intestines will compromise with their individual positions. As your uterus will grow, your uterus may be pushed behind it. This may make your belly appear bigger or similar to the size of the baby. And, in case the intestines may find a place near the uterus edges, the belly may look bulged out from the sides as well.

Gas And Pregnancy Bloating
Changes in your gastrointestinal tract are a normal part of pregnancy. Excessive gas and bloating affect lots of people, especially in the first trimester. Pregnant people may also experience constipation, especially by the second trimester. This is because of hormones that relax the intestinal muscles and the pressure of the expanding uterus on the intestines. As a result, food and waste move more slowly through your system. Increased protein intake and pregnancy vitamins with iron may also contribute to constipation.

From Conception To 12 Weeks
From conception to 12 weeks of pregnancy the uterus is contained within the bones of the pelvis and cannot be felt through the belly. After about 12 weeks, the uterus is large enough to be felt above the pelvis by your caregiver , usually just being able to touch the very top of the uterus or fundus.
Some women having second+ babies find their uterus is a little more bulky from previous pregnancies, making it being able to be felt earlier, possibly after about 10 or 11 weeks. This is also the case if you are having twins or more. If you feel you are 12 weeks pregnant or more and your uterus cannot be felt by your caregiver, it may be that you are not as far pregnant as you first calculated, or perhaps it is a physical sign of a missed miscarriage.
