Clinical Updates in Reproductive Health

Who has abortions at 13 weeks or later?

Last reviewed: October 11, 2022

Key Information:

  • People who present for abortion at 13 weeks of pregnancy or later are more likely than those who present at earlier gestations to be young or a victim of violence, have detected their pregnancy later, feel ambivalent about the abortion decision, and/or have financial and logistical barriers to care. Additionally, medical or fetal indications for an abortion may not be apparent until after 13 weeks. Reasons for presenting at or after 13 weeks gestation appear similar across countries and cultures and disproportionately affect underserved people.

Quality of evidence: Low

Epidemiology of abortion at 13 weeks and later

While abortions at or after 13 weeks gestation comprise a minority (around 10-15%) of the total abortions worldwide, they are responsible for the majority of serious abortion-related complications . In more restrictive settings, or where safe abortion access is limited, presentation at or after 13 weeks gestation for postabortion care is more common. In Cambodia 17%, in Ethiopia 38%, and in Kenya 41% of individuals needing postabortion care present at or after 13 weeks gestation. (African Population and Health Research Center et al., 2013; Fetters et al., 2008; Gebreselassie et al., 2010).

Why do people need abortions at 13 weeks and later?

Young age: Young people are disproportionately likely to seek abortion at or after 13 weeks (Espinoza, Samandari, & Andersen, 2022). In the United States, 23.7% of those younger than age 15 and 12.4% of adolescents ages 15-19 seeking abortion care do so after 13 weeks gestation In Mexico City, adolescents comprised 9% of all women seeking abortion from 2007-2015; yet, they accounted for 13% of women seeking abortion beyond 12 weeks gestation (Saavedra-Avendano et al., 2018). Smaller studies in Ethiopia, India, Kenya, Nepal, Singapore and the United States have found young age to be a risk factor for later presentation (Bonnen, Tuijje, & Rasch, 2014; Foster & Kimport, 2013; Lim, Wong, Yong, & Singh, 2012; Sowmini, 2013; Ushie et al., 2018).

Late detection of pregnancy: A common risk factor in all studies for presenting for abortion at or after 13 weeks is late recognition of pregnancy. Poor understanding and awareness of fertility and pregnancy signs and symptoms affects individual recognition of pregnancy (Somefun, Harries, & Constant, 2021), particularly among young people (Espinoza, Samandari, & Andersen, 2020). Absence of pregnancy signs and symptoms, menstrual irregularity, contraceptive use, or amenorrhea after recent pregnancy can mask physical signs of pregnancy and delay pregnancy diagnosis (Constant et al., 2019; Drey et al., 2006; Foster, Gould, & Biggs, 2021; Foster & Kimport, 2013; Gallo & Nghia, 2007; Harries et al., 2007; Ingham et al., 2008; Jones & Jerman, 2017; Purcell et al., 2014). In one case-control study in the United States, women who sought abortion after 20 weeks were much more likely to have been eight weeks pregnant or more at the time they discovered they were pregnant (68%), compared to women who had abortions before 13 weeks gestation (12%) (Foster & Kimport, 2013).

Ambivalence and/or difficulty with abortion decision: People’s decision making may be delayed due to social pressures, fears, religious attitudes and changes in relationship status. Changes in circumstance (such as abandonment by partner) cause some  to seek an abortion after initially planning to continue the pregnancy (Foster & Kimport, 2013; Gallo & Nghia, 2007; Harries et al., 2007). Discouraging family and friends may also delay care-seeking (Waddington, Hahn, & Reid, 2015).

Financial and logistical barriers: Poverty (Goyal et al., 2020; Sium et al., 2022; Usta et al., 2008), immigrant status (Gonzalez-Rabago et al., 2017; Loeber & Wijsen, 2008), rural residence (Bonnen et al., 2014; Ushie et al., 2018), unemployment (Gonzalez, Quast, & Venanzi, 2019; Van de Velde et al., 2019), and lack of health insurance (Raidoo et al., 2020) are risk factors for presentation for abortion care at or after 13 weeks gestation. Delays may be related to raising enough money to cover the cost of the procedure, particularly as procedures later in gestation are more expensive (Foster & Kimport, 2013; Kiley, Yee, Niemi, Feinglass, & Simon, 2010). Abortions at or after 13 weeks gestation are provided at a limited number of facilities and travel logistics present difficulties for many (Goyal et al., 2020; Sium et al., 2021; White et al., 2021). In one case-control study of women presenting for abortion at over 20 weeks gestation, were much more likely than those within earlier gestations to have travelled over three hours to access care (Foster & Kimport, 2013). Clients at 13 weeks gestation or later may be referred by other providers or have trouble finding a provider before finally accessing care (Drey et al., 2006; Harries et al., 2007). Women may also need to travel out of their own country to access legal abortion after 13 weeks ( Cameron et al., 2016; Loeber & Wijsen, 2008).

Fetal indications: Prenatal diagnosis of fetal anomalies typically occurs after the first 12 weeks of pregnancy, and women may make the decision to terminate pregnancy based on the diagnosis (Edling, Lindstrom, & Bergman, 2021; Lyus et al., 2013).

Maternal indications: Medical conditions that worsen during the course of pregnancy or a new condition may arise in pregnancy may endanger the life or health of the pregnant person (Kiver, Altmann, Kamhieh-Milz, & Weichert, 2019). Severe preeclampsia or preterm premature rupture of membranes may require termination of pregnancy to save a pregnant person’s life (American College of Obstetricians and Gynecologists, 2015).

Victims of violence: Victims of violence have a higher risk of late presentation (Colarossi & Dean, 2014; Perry et al., 2015). Adolescents and young people, particularly those aged 10-14 years, are more likely to have a pregnancy due to rape, incest or transactional sex, and to subsequently present later in pregnancy for abortion (Espinoza, Samandari, & Andersen, 2020).

Failed abortion: Although failures are rare, those who experience an ongoing pregnancy after an abortion before 13 weeks may not discover they are still pregnant until after 13 weeks gestation (Gallo & Nghia, 2007).

Cultural beliefs: In rare cases there are local beliefs that having an abortion at 13 weeks or later is safer than the first 12 weeks of pregnancy, thus causing a delay in care-seeking (Marlow et al., 2014).
