when I attend the pre-natal class in the hospital, the nurse explained this is very normal for pregnant woman and woman after giving birth.
In the old days, like our mother's generation, they are not educated about this, and not many talk about it.
Now, the nurse tries to educate more woman. It's very very normal. and that's why it's so important to do 'exercise' during pregnancy and after giving birth.
the exercise tried to contract the muscle, just like holding your pp; then relax, then contract again....
10-15 times a day.
easy to do.
this will strengthen the muscle, and improve or avoid the problem.
