Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The purpose of this study is to demonstrate reproducibility of earlier findings in a more heterogenous population. As such, IUD placement is not a study procedure but a component of clinical care. The study interventions only involve study participation and provision of data around the use of the levonorgestrel 52 mg IUD for EC or same day start.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
However, the LNG 52 mg IUD prescribing information and Centers for Disease Control and World Health Organization clinical guidelines, which guide clinical care outside of PPFA, currently oppose placement for both of these situations. The current recommendation for those not within the first 7 days of the menstrual cycle is to delay LNG IUD placement and return after the next menses start. We found in the RAPID EC trial and other analyses that the risk of pregnancy appears negligible when initiating an LNG 52 mg IUD for EC or same-day start, provided the urine pregnancy test is negative. This study assesses reproducibility of RAPID EC's findings by determining the effectiveness of the LNG 52 mg IUD to prevent pregnancy in real-world settings where users select their treatment (and are not randomized to it as in RAPID EC trial). We will test reproducibility and generalizability in a larger, more diverse population to assess the appropriateness of defining the interventional IUD as a new standard of care and how PPFA guidelines should be revised before influencing guidelines more broadly.
EC: Pills, the copper IUD, and the importance of adding the LNG 52 mg as a new EC option
Globally, people use EC methods to decrease their risk of pregnancy after UPI because of method failure or not using contraception. EC use in the U.S. is common and increasing. In 2002, 4% of pregnancy capable people ever reporting sexual intercourse had used EC. This figure climbed to 20% by 2015, and to 27% by 2017 for urban women. Although anyone can obtain oral EC without a prescription, IUDs can be desirable for EC because they are much more effective than EC pills and provide ongoing highly effective contraception for years if desired. So, while the majority of EC users do not want an IUD it is an important option with distinct benefits for those that do.
In the U.S., the Food and Drug Administration (FDA) has approved only two methods of EC: oral LNG and oral ulipristal acetate. A third method, the copper IUD, is an evidence-based EC approach and the most effective (failure rate \<0.1%), with pregnancy risk an order of magnitude lower than the oral methods. However, those selecting an IUD for long-term contraception are more likely to choose the LNG over the copper IUD. Adding the LNG 52 mg IUD as another EC option, highly effective for both EC and ongoing contraception, is a significant advancement. Especially given that a greater number of contraceptive options presented to an individual is associated with increased method satisfaction, continuation, and decreased unintended pregnancy. The RAPID EC trial demonstrated efficacy for the first new EC method since the 2010 FDA approval of oral ulipristal acetate.
Oral EC methods are less effective in two critical situations where IUD EC efficacy does not change.
One, for people with a Body Mass Index (BMI) \>30 kg/m2 the risk of pregnancy risk after oral EC rises to 2.6% for ulipristal users and to 5.8% for oral LNG EC users, approaching no effect. However, IUD pregnancy risk does not change with weight for either EC (half of RAPID EC participants had a BMI 25 or greater) or ongoing contraception. Public health significance of this issue increases as the mean BMI for U.S. women of reproductive age rises toward 30 kg/m2. Two, the absolute highest risk of pregnancy for oral LNG EC users, 7.3%, is in women reporting additional acts of intercourse later in the cycle after EC use. This elevated risk of pregnancy is eliminated when an IUD is placed for EC as supported by a RAPID EC secondary analysis.
Same-day LNG IUD start reduces ongoing pregnancy risk and promotes autonomy.
"Same-day start" describes the need to provide people their desired method of contraception on the day they present for care. Meeting people's needs on the day they present for care is important because requiring two visits for IUD placement for STI testing, which is unnecessary to reduce infection risk, or additional counseling sessions, results in only half (54%) returning to get the IUD. Adolescents, post-abortion, and postpartum patients who receive long acting reversible contraceptive (LARC) methods when presenting for care, rather than returning later, are more likely to get their desired method and have lower pregnancy rates. Same-day LARC access is supported by The American College of Obstetricians and Gynecologists, but is only provided by 29% of U.S. Obstetrician Gynecologists.
Provision of the LNG IUD for EC and same-day start use is an important step in removing access barriers to contraception and providing people with the method they desire at the time that they present for care. We hypothesize both reproducibility of the initial results and greater generalizability. This effectiveness study will expand on the previous trial, conducted in one geographic area, by enrolling a heterogeneous participant population from 8 U.S. PPFA affiliates, providing geographic, racial, ethnic, and gender diversity.

52 mg LNG IUD Same Day Start or EC
Week 1: Text daily for seven days. Report occurrences of the following in the last day: presence or absence of bleeding, spotting, pain, sexual intercourse, use of other methods of contraception, IUD expulsion or removal, and report any additional medical care received.
Weeks 2 \& 3: Weekly text survey assessing on which days of the previous week participants experienced bleeding and spotting, sexual intercourse, use of other methods of contraception, IUD expulsion or removal, or experienced adverse events.
Week 4 Survey: At 28 days, participants will be asked about pregnancy symptoms, concern about pregnancy, and the result of their urine pregnancy test including a prompt to upload a photo of the test.
