子宫收缩:如何判断什么是正常的
It is normal to have some uterine contractions throughout the day. They often occur when you change positions, such as from sitting to lying down. It is not normal to have frequent uterine contractions, such as six or more in one hour. Frequent uterine contractions or tightenings may cause your cervix to begin to open.
Since the onset of premature labor is very subtle and often hard to recognize, it is important to know how to feel your abdomen for uterine contractions. 你可以这样感受宫缩:
- While lying down, place your fingertips on the top of your 子宫
- A contraction is a periodic tightening or hardening of your 子宫. 如果你的子宫在收缩, you will actually feel your abdomen get tight or hard, and then feel it relax or soften when the contraction is over.
