Hi Eva

From what I've read and heard it could, I don't know the exact hormone in your pill but I recently asked my Doc for HRT and was told it was too early but the pill would be appropriate but would probably cause weight gain. I know many people do gain weight on the pill, since you have not gained but not lost maybe you are as you said going through a period of adjustment. However it is you won't gain as much as yo would getting pregnant There's a whole list of medications Atkins says can interfere with this diet and if I remember correctly hormonal meds are on that list.
