Is it possible to abort a baby after 3 month and how?

It would be by surgery. The dilation and suction curettage method can be done week 6-14 after your last period. They will numb your cervix and slowly dilate it and then scrape the uterus wall with a small, narrow metal loop called a curette. The curette is used to clean the walls to be sure no tissue remains. it takes about 10 minutes.
