Brief summary:
The primary goal of this project is to investigate the potential efficacy of exogenous progesterone (with supplemental relapse prevention counseling) on postpartum relapse in new mothers. Also to determine the feasibility of enhanced compliance monitoring and identification of collateral factors effecting outcomes.

Detailed description:
Pregnant women will be recruited at gestational weeks 33-36 who have quit smoking during pregnancy and are motivated to maintain abstinence after delivery. At the time of delivery, women will be randomly assigned to receive 4 weeks of active or placebo exogenous progesterone starting on the 4th day postpartum. Participants will be in contact with study staff either by phone or clinic visits until 12 weeks postpartum to collect data on smoking status and protocol compliance, measure serum progesterone levels and receive behavioral counseling.

Arms:
arm 1: Take micronized natural progesterone capsule by mouth, twice daily (approximately at 8 am and 8 pm) for four weeks beginning on postpartum day 4. arm 2: Take placebo capsule by mouth, twice daily (approximately at 8 am and 8 pm) for 4 weeks beginning on postpartum day 4.

Interventions: intervention 1: Progesterone intervention 2: Placebo
Intervention descriptions: intervention 1: Take micronized natural progesterone capsule by mouth, twice daily (approximately at 8 am and 8 pm) for four weeks beginning on postpartum day 4. intervention 2: Take placebo capsule by mouth, twice daily (approximately at 8 am and 8 pm) for 4 weeks beginning on postpartum day 4.
