My 13 yr old daughter was given yasmin because irregular periods. Bleeding all the time. she got regulated but after reading this site i realize why she has had the awful side effects that she has had. She started taking y around october of last year. She plays competetive soccer and she was not able to keep up ..Shortness of breath tiredness looked as though she was out of shape. We never thought it could be those y pills. never crossed our mind. march she was diagnosed with mono so we just decided to take her off because she had mono. she has not had y since march and she is still tired all the time. back hurts hot flashed heat intolerant. will this y leave her system soon?
