No, not a problem at all - I've been on Yasmin since the beginning of this year - so January. I have temporarily stopped taking it for the time being due to some elective surgery I had. I didn't want to risk blood clots. I had my surgery 2 weeks ago and at the time I was on my white pills from the pack and I had my period. I never went back on the pill by starting a new pack, so this week since Monday I've had a period. I'll probably wait until my next period comes next month to start back up on a new pack again. I should be healed pretty well by then.
I cannot tell you an exact number of pounds I've lost because I don't ever weigh myself. I would estimate though that at least 5 pounds dropped off, but I'm guessing that to be water weight due to the dieretic in Yasmin. Prior to my surgery, I exercized about 5 yo 6 times a week for an hour. Usually riding my stationary bike and lifting some hand weights. I just started the biking since November to tone up my buns and thighs. Anyhow, my clothes are loose and I feel like I look better while I"m on Yasmin...lately I've feel kind of bloated and frumpy again so I'm looking forward to going back on it.
