Abstract
Objectives: To prospectively evaluate (1) pregnancy desirability, (2) stated intentions should pregnancy occur among emergency contraception (EC) users, and (3) explore differences between women selecting the copper T380 intrauterine device (Cu IUD) or oral levonorgestrel (LNG) regarding hypothetical pregnancy plans and actual pregnancy actions during subsequent unintended pregnancies.
Study design: In this prospective observational trial, women received the Cu IUD or oral LNG for EC without cost barriers. At baseline, participants completed a visual analogue scale measuring pregnancy desirability (anchors: 0, "trying hard not to get pregnant"; 10, "trying hard to get pregnant") and self-reported plans (abortion, adoption, parenting, and unsure) if the pregnancy test were to come back positive. Pregnancies were tracked for 12 months, and actions regarding unintended pregnancies were compared between EC method groups.
Results: Of 548 enrolled women, 218 chose the Cu IUD and 330 the oral LNG for EC. Pregnancy desirability at baseline was low, with no difference between EC groups (IUD group: 0.51, SD ± 1.60; LNG group: 0.68, SD ± 1.74). Fifty-four (10%) women experienced unintended pregnancies. Pregnancy plans from baseline changed for 27 (50%) women when they became pregnant. EC groups did not differ in hypothetical pregnancy intention (p = 0.15) or in agreement of hypothetical pregnancy intention with actual pregnancy action (p = 0.80).
Conclusions: Women presenting for EC state high desire to prevent pregnancy regardless of method selected. When considering a hypothetical pregnancy, half of women had a plan for how they would respond to that situation, but when confronting an actual unintended pregnancy, half altered their plan.
