Abortion ends a pregnancy using either medication or a procedural (surgical) approach, depending on how far along the pregnancy is. Most abortions in the United States happen in the first trimester, and the method used shapes what the experience feels like, how long it takes, and what recovery looks like. Here’s what actually happens with each approach.
Medication Abortion (The Abortion Pill)
Medication abortion uses two drugs taken in sequence, typically up to 10 or 11 weeks of pregnancy. The first drug blocks progesterone, the hormone that maintains the uterine lining and supports early pregnancy. Without progesterone, the lining begins to break down. This drug also makes the uterus more responsive to the second medication, which triggers contractions that expel the pregnancy tissue. The process is similar to a heavy, crampy period, though the intensity varies from person to person.
The first pill is usually taken in a clinic or at home. The second is taken 24 to 48 hours later, often placed between the cheek and gum or inserted vaginally. Most people pass the pregnancy tissue within a few hours of taking the second medication, though it can take longer. Bleeding and cramping are the primary physical experiences, and both are expected parts of the process.
Effectiveness depends on how far along the pregnancy is. At 8 weeks or less, the two-drug regimen works 94 to 98 percent of the time. That drops slightly to 94 to 96 percent at 8 to 9 weeks, 91 to 93 percent at 9 to 10 weeks, and about 87 percent at 10 to 11 weeks. When it doesn’t work completely, a follow-up procedural abortion is typically needed. An ongoing pregnancy after medication abortion occurs in roughly 0.5 percent of cases.
Aspiration Abortion (First Trimester)
Aspiration abortion, sometimes called vacuum aspiration or suction abortion, is the most common procedural method in the first trimester. It’s done in a clinic or outpatient setting and is much faster than most people expect.
The clinician uses a speculum to visualize the cervix, then cleans it with an antiseptic solution. A numbing medication is applied to the cervix and uterus. If you’re 10 or more weeks pregnant, you may receive a medication beforehand to soften the cervix and make dilation easier. The cervix is then gradually opened using thin rods, a narrow flexible tube is inserted into the uterus, and gentle suction removes the pregnancy tissue.
The entire appointment typically lasts 15 to 20 minutes, but most of that time is preparation. The suction itself takes only one to five minutes. Many people describe the sensation as strong cramping that eases quickly once the suction stops.
Dilation and Evacuation (Second Trimester)
For pregnancies beyond the first trimester, typically after 14 to 16 weeks, a procedure called dilation and evacuation (D&E) is used. It has two stages: preparing the cervix and then removing the pregnancy tissue.
Because the cervix needs to open wider at this stage, preparation often begins one or two days before the procedure. Small absorbent rods are placed in the cervix, where they gradually expand as they absorb moisture. Medications may also be used to help soften and dilate the cervix further. On the day of the procedure, the clinician uses a combination of suction, specialized instruments, and sometimes a curette (a thin, spoon-shaped tool) to empty the uterus. An ultrasound is standard before any second-trimester procedure to check the placenta’s location and confirm the pregnancy’s size.
Pain Management Options
What you’ll feel and what pain relief you’re offered depends on the type of abortion and how far along the pregnancy is. For first-trimester aspiration, local numbing at the cervix is standard. Many clinics also offer moderate sedation through an IV, which keeps you awake but relaxed and less aware of discomfort. Some clinics provide deeper sedation or general anesthesia, particularly for second-trimester procedures, where research shows it’s the most effective approach for pain control.
For medication abortion, most people manage pain at home with ibuprofen and a heating pad. The cramping can range from moderate to intense, especially in the hours right after taking the second medication, then gradually subsides.
What Happens Before the Procedure
Before any abortion, a pregnancy test confirms the pregnancy and an ultrasound may be performed to determine how far along it is, check for an ectopic pregnancy (one located outside the uterus, which requires different treatment), and note any uterine abnormalities. Blood type testing is sometimes done to check for Rh-negative status, though medical guidelines differ on whether this is necessary in the first trimester. Screening for sexually transmitted infections like chlamydia or gonorrhea is common, particularly for people under 25. Additional blood work is only needed if you have a relevant medical history, such as a bleeding disorder or liver disease.
Recovery and What to Expect After
After either a medication or procedural abortion, bleeding is normal and can last up to a week, or come and go for up to four weeks. Cramping typically lasts a few days. Most people return to normal activities within a day or two after a first-trimester procedure, though medication abortions may involve a longer stretch of intermittent symptoms since the process unfolds over hours or days.
Complications are uncommon. About 2 percent of abortions involve any complication at all, and only about one in four of those (roughly 0.5 percent overall) require additional intervention or hospitalization. Signs that warrant a call to your provider include a fever over 100 degrees, soaking through one pad per hour for three consecutive hours, or severe cramping that doesn’t respond to over-the-counter pain relievers.
Most people can get pregnant again within two to four weeks after an abortion, so contraception is worth discussing at your follow-up if you want to prevent another pregnancy.
