Measure
Low-Dose Contraceptive, Then High-Dose
Females, 18-35 years old, non-pregnant, using oral contraceptive for at least the last 3 months before enrollment will be given Tri-Sprintec and generic Prometrium. Participants in this arm will begin with the "low" dose progesterone, which is seven days of placebo Tri-sprintec + placebo generic Prometrium twice daily (7AM and 7PM). Then participants in this arm will move to the "high" dose progesterone, which is seven days of placebo Tri-Sprintec + 200mg of generic Prometrium twice daily (7AM and 7PM).
High-Dose Contraceptive, Then Low-Dose
Females, 18-35 years old, non-pregnant, using oral contraceptive for at least the last 3 months before enrollment will be given Tri-Sprintec and generic Prometrium. Participants in this arm will begin with the "high" progesterone dose, which is seven days of placebo Tri-Sprintec + 200mg of generic Prometrium twice daily (7AM and 7PM). Then participants in this arm will move to the "low" dose progesterone, which is seven days of placebo Tri-sprintec + placebo generic Prometrium twice daily (7AM and 7PM).

Measure
High-Dose Contraceptive
n=36 Participants
Females, 18-35 years old, non-pregnant, using oral contraceptive for at least the last 3 months before enrollment will be given a high-dose contraceptive. The "high" progesterone dose is seven days of placebo Tri-Sprintec + 200mg of generic Prometrium twice a day (7AM and 7PM).
Low-Dose Contraceptive
n=34 Participants
Females, 18-35 years old, non-pregnant, using oral contraceptive for at least the last 3 months before enrollment will be given a low-dose contraceptive. The "low" progesterone dose is seven days of placebo Tri-sprintec + placebo generic Prometrium twice a day (7AM and 7PM).

SECONDARY outcome

Timeframe: after overnight abstinence on day 8

Positive and Negative Affect Scale (PANAS): Participants rate 20 words associated with positive or negative affect using a five-point Likert-type scale. This scale has been shown to have high internal consistency. Positive PANAS scores can range from 10-50. A higher score means greater positive affect. Negative PANAS score can range from 10-50. A higher score means greater negative affect.

SECONDARY outcome

Timeframe: after overnight abstinence on day 8

Cohen Perceived Stress Scale (PSS): This ten-item questionnaire has been validated in a variety of populations including pregnant and postpartum women. It uses five-items to assess ten questions resulting in two factors negative feelings and inability to handle stress. It has high internal reliability (alpha = 0.75). Score range from 0-56. A higher score means more perceived stress.
