Home pregnancy test use and timing of pregnancy confirmation among people seeking health care.

Objectives: Understanding the timing of pregnancy suspicion and confirmation, including the role of home pregnancy tests, can facilitate earlier entry into pregnancy-related care and identify individuals likely to be impacted by gestation-based abortion restrictions.
Study Design: We use data from 259 pregnant individuals participating in a cross-sectional survey at 8 primary and reproductive health care clinics in 6 U.S. states (2016-2017). We use regression models to identify differences in utilization of HPTs, barriers to use, and to compare gestational duration at pregnancy confirmation.
Results: Three-quarters (74%) of respondents took a home pregnancy test as the first step in confirming pregnancy; this figure was lower among adolescents versus young adults (65 vs 81%, p = 0.01). Two-thirds (64%) reported delays in home testing, higher among adolescents (85%). People taking a test at home confirmed pregnancy 10 days earlier than those first testing at a clinic (41.3 vs 51.8 days gestation, p = 0.02). Those that did not test at home cited concerns about test accuracy (42%) and difficulties accessing one (26%). While overall 21% confirmed pregnancy at ≥7 weeks gestation, and 35% at ≥6 weeks, confirmation at ≥7 weeks was higher among adolescents versus young adults (47 vs 13%, p = 0.001), Latina versus white women (28 vs 11%, p = 0.02), food insecure versus secure women (28 vs 17%, p = 0.06), and people with unplanned versus planned/mistimed pregnancies (25 vs 13%, p = 0.07).
Conclusions: Home pregnancy testing is common and associated with earlier pregnancy confirmation. Still, barriers to at-home testing are evident, particularly among adolescents. Efforts to expand access to home pregnancy tests and increase knowledge about their accuracy may be impactful in increasing utilization.
Implications: While at home pregnancy testing is common and facilitates earlier confirmation of pregnancy, one in 5 confirm pregnancy at 7 weeks gestation or later (and one in 3 do so at 6 weeks or later). Gestational bans in the first trimester will disproportionately prevent young people, people of color, and those living with food insecurity from being able to access abortion.
