Measure
Normal BMI ECx1
5 normal weight women (BMI\<25 kg/m2) taking 1.5mg LNG ECx1: At the first treatment visit, all women will be given the study drug (1.5 mg of levonorgestrel) and several blood samples will be taken over 2.5 hours). After this visit, women with a BMI of \<25 kg/m2 will have completed study participation.
Obese BMI ECx1
5 obese women (BMI \>30 kg/m2) taking 1.5mg LNG ECx1: At the first treatment visit, all women will be given the study drug (1.5 mg of levonorgestrel) and several blood samples will be taken over 2.5 hours). After this visit, women with a BMI of \<25 kg/m2 will have completed study participation.
Obese BMI ECx2
5 obese women (BMI \>30 kg/m2) taking 3mg LNG ECx2: At the first treatment visit, all women will be given the study drug (1.5 mg of levonorgestrel) and several blood samples will be taken over 2.5 hours). For women with a BMI of 30kg/m2 and greater, one additional visit will be required and study drug (3 mg of levonorgestrel) will be given and several blood samples will be taken over 2.5 hours)
