How many times can an abortion be performed without pain?

Patient's question:

Just found out, tested with a test strip

Doctor's answer:

Generally speaking, regardless of the type of painless abortion, it is best not to exceed 3 times, and the interval between each painless abortion should be at least half a year. Because abortion uses artificial methods to remove the embryo tissue attached to the endometrium. The more times it is done, the more likely it is to cause some damage to the endometrium.
