Hi my name is Jenny and i am 20 years old! I weigh 190 pounds and i am very tall!( i think about 5.9 :s) i have no health problems at all :) I have started to use Yaz Birth control pill for the first time when my period started and on the fourth day i stopped cause the side effects were too much for me!! my period sorta of stoped on the 7th day but 2 days later i started to bleed again! I am very worried because i have never had this experience before!! :( And i been reading so much about yaz that it scares me... PLS Help! :) Thank You!
