I have been on again, off again with yasmin for about nine months. I've been off it for 3 months, but i just started up again less than a week ago! Within a couple days, I felt off: depressed(for no particular reason), nervous, anxious, etc. Because I'm usually a perky, happy-go-lucky person, my family and I decided it was surely because of the pill. I have made an appointment at my gyno and I know I'm going to get off the pill right away, but I'm scared to think that my symptoms will still occur even after I've been off it for awhile. Does anyone have any idea of a time frame? Or advice?
