### Chinese: 时间长度、血量、痛经程度因人而异，有些人三天，有些人一周；有些人流的少，有些人大血崩；有些人没什么反应，有些人疼到救护车运走，痛经随着时间会改变，以前不痛不代表一辈子不痛。
### English: The length of time, blood volume, and degree of dysmenorrhea vary from person to person. Some people have three days, some have a week; some people have less flow and some people have massive bleeding; some people don't <v>respond</v>; some people feel pain until they are taken away by ambulances. Dysmenorrhea will change over time. The pain in the past does not mean the pain in the entire life.

### Improved English: The length of time, blood volume and degree of dysmenorrhea vary from person to person; some people have it for three days and some people a week; some people have small flow and some people have way too much; some people don’t have any reaction, and some people feel so painful that they have to be taken away by the ambulance; dysmenorrhea will change over time, and not having it before doesn’t mean it won’t happen for a lifetime.
