Uncommon. Risks of an abortion procedure include bleeding, infection, perforation of the uterus with or without injury to nearby organs (bladder, bowel, blood vessels) which may necessitate further surgery, uterine scarring (may affect future fertility). Fortunately, these risks are quite low, and most women experience no complications.
Abortion Problems. Abortions usually do not cause infertility problems later. However, any procedure can have complications like infection or retained pg tissue. The more abortions you have then the more likely it is that a problem might happen. You would be well advised to avoid pregnancy than to have an abortion on many levels. Good luck.
