Brief Summary
A well-designed pharmacokinetics (PK) study may identify the physiologic basis for observed differences in levonorgestrel emergency contraception (LNG-EC) and ulipristal acetate emergency contraception (UPA-EC) failure rates in women with normal and obese BMI. The investigators propose a study to compare serum LNG and UPA levels after administration of a single-dose of LNG-EC or UPA-EC. The investigators hypothesize that there will be no difference in PK parameters between women with normal BMI and obese women.

Study Arms (2)
Normal-BMI
OTHERWomen with normal BMI will receive the first emergency contraception (EC) dose and complete pharmacokinetics (PK) assessments; then return to the clinic after at least 8 days to receive the second study drug and complete the same assessments. The study drugs Levonorgestrel (LNG-EC) and Ulipristal Acetate (UPA-EC) will be given in random order.
Obese-BMI
OTHERWomen with obese BMI will receive the first emergency contraception (EC) dose and complete pharmacokinetics (PK) assessments; then return to the clinic after at least 8 days to receive the second study drug and complete the same assessments. The study drugs Levonorgestrel (LNG-EC) and Ulipristal Acetate (UPA-EC) will be given in random order.
Interventions
FDA-approved emergency contraceptive pill containing levonorgestrel 1.5mg
FDA-approved emergency contraceptive pill containing ulipristal acetate 30mg
