What generation pill is it?
I went psycho on one. Loette. YUCK.
I thought it was me but friends also had issues on it. It was right after there were scares about 3rd generation contraceptives and blood clots. So drs here were putting girls on 2nd generations as a precaution, but they seem to have worse side effects.
Most of us just went back on 3rd generations, as long as we didn't have any real risk factors.
I now take one called Yasmin - it apparently has the closest possible to progesterone (i think that's the one) and it makes absolutely no difference to my mood, skin, or weight
Good luck with your situation.
