"i was put on yaz about 5 weeks ago.at first i had no side effects.after i started the second set i started bleeding.it has been ongoing for 10 days now and all i wanna do is cry.i have no energy.and it did not help with straightening out my period like the doctor said it would.i stopped taking it and i feel better just gotta figure out y i&#039;m still bleeding.the doctor said i was primenaposal. i seriously doubt birth control can help with that.i&#039;m ready for second opinion.i will never take yaz ever again.plus the pain was 10 times worse."
