There is no medical limit on the number of abortions a person can have. No professional medical body sets a maximum, and having more than one abortion is common. CDC surveillance data from 2022 shows that about 44% of abortions were among people who had at least one previous abortion, with roughly 8% reporting three or more prior procedures. That said, each procedure carries a small amount of risk, and some of those risks increase slightly with repetition, particularly for surgical methods.
How Common Are Repeat Abortions?
Among the 41 reporting areas that provided data to the CDC in 2022, about 24.7% of abortions were among people who had one previous abortion, 10.9% had two, and 8.2% had three or more. So while most abortions are a person’s first, nearly one in five involved someone with two or more prior procedures. Repeat abortions are a routine part of reproductive healthcare, not an outlier.
Medication vs. Surgical: How Method Matters
The two main types of abortion carry different risk profiles when repeated. Medication abortion (using pills to end a pregnancy) does not involve any instruments entering the uterus, so there is no physical trauma to cervical or uterine tissue. There is no known cumulative risk from having multiple medication abortions. Success rates sit around 95 to 97%, with 3 to 5% of patients needing a follow-up aspiration procedure.
Surgical abortion (aspiration or dilation and curettage) is slightly more relevant when thinking about repeat procedures. It is highly effective, succeeding about 98% of the time, but it involves dilating the cervix and using suction or instruments inside the uterus. Most of the physical risks associated with multiple abortions are tied to this method specifically.
Uterine Scarring
The primary concern with repeated surgical abortions is the formation of scar tissue inside the uterus, a condition called Asherman syndrome. This can cause lighter periods, pelvic pain, or difficulty getting pregnant later. The Mayo Clinic notes that while this condition is rare, the risk is higher after undergoing dilation and curettage more than once. Medication abortions do not carry this risk because no instruments contact the uterine lining.
Cervical Weakness and Preterm Birth Risk
Repeated surgical abortions can affect the cervix. A systematic review published in Reproductive Sciences found that the odds of cervical insufficiency (where the cervix opens too early in a future pregnancy) increased with each additional abortion. After one abortion, the odds were about 2.5 times higher than baseline. After two, about 4.7 times. After three, roughly 8 times. After four or more, about 12 times higher. Cervical insufficiency can lead to preterm birth or pregnancy loss in the second trimester, so this is one of the more meaningful risks to understand if you plan to carry a pregnancy in the future.
A large Scottish cohort study published in BMJ Open found that surgical abortion increased the risk of spontaneous preterm birth by about 25% compared to medication abortion. However, the same study found something reassuring: among people who had two or more consecutive abortions, the risk of preterm birth did not keep climbing with each additional procedure. The elevated risk appeared to plateau rather than stack indefinitely.
Impact on Future Fertility
For most people, having one or more abortions does not cause infertility. Ovulation typically resumes within weeks, and the uterus heals quickly after both medication and surgical procedures. The main fertility concern is Asherman syndrome from repeated surgical procedures, but even that remains uncommon. If you’ve had multiple surgical abortions and later have trouble conceiving or notice significantly lighter periods, scar tissue is worth investigating, but it’s treatable.
The Scottish cohort study did find higher rates of certain pregnancy complications (pre-eclampsia, placental abruption, low birth weight) in people with a history of induced abortion compared to those with a previous live birth. These were population-level associations, not guarantees of individual outcomes, and the absolute risk increases were modest.
What Actually Determines Safety
The safety of any individual abortion depends far more on the gestational age, the method used, and the skill of the provider than on how many you’ve had before. Earlier abortions are simpler and carry fewer complications regardless of your history. Medication abortions, available through the first 10 to 12 weeks, involve the least physical risk overall and leave no cumulative trace on the uterus or cervix.
If you are considering or have had multiple abortions and want to become pregnant in the future, the most practical thing to know is that medication abortions carry essentially no known compounding risk, while repeated surgical procedures slightly increase the chances of cervical weakness and uterine scarring. Neither scenario makes future pregnancy impossible, but the distinction between methods is worth keeping in mind when you have a choice.
