1, especially during pregnancy.
When I was just pregnant, my mother usually had a pregnancy reaction. If it is twins, the pregnancy reaction will be particularly strong. Pregnancy reactions such as loss of appetite, nausea and vomiting, morning sickness and edema will be much larger than those of singletons.
2. The abdomen is bigger and more prominent.
A single child takes up a lot of space in a mother's stomach, so it naturally needs more space to conceive two babies. On the other hand, pregnant twins need more nutrition from their pregnant mothers.
3. The progesterone value and hcg value are high.
Pregnant women with twins usually have higher progesterone and HCG values in the early pregnancy than pregnant women with one child. For example, in the seventh week of pregnancy, the normal value of progesterone is 52.7- 100. 1nmol/L, and it may be higher if it is twins.
4. More than one heartbeat
With the increase of pregnancy time, if it is twin pregnancy symptoms, twin pregnancy symptoms can touch two fetal heads and two fetal hips and hear two fetal heart sounds.
5. The uterus is bigger
Obviously, two babies need to occupy more uterine space. When doing a pregnancy test, if it is found that the size of the uterus in the eighth week of pregnancy is similar to that in the eleventh week of others, if the possibility of disease is ruled out, it is more likely to be pregnant with twins.
6. The fetus moves in different directions
Some mothers feel that there is more than one fetus in their bellies because they feel continuous fetal movements in different directions. This is also a sign of having twins.
7. Family orientation
Although nothing can increase the chances of having identical twins, there are still some reasons that make it easier for women to have fraternal twins.
8, systemic symptoms are more obvious.
In addition to the serious pregnancy reactions mentioned above, dizziness, fatigue, chills, loss of appetite and other early pregnancy reactions are more obvious.
9. The abdomen grows rapidly.
Because there are two babies in the belly, when the two babies grow up together, the abdomen will grow faster than the single baby.
