Hey i'm 16 and i was a Yasmin for a couple of months the first month i had my period for 30days then i came off it for a month went back on it the next and that month 2 weeks into i got cluster migraines that were so severe i ended up in hospital 3 times getting shot up with methadone to try and stop the pain and break the cycle, i had a week of the cluster migraines where i was having up 2 to four a day. Although i did notice when taking it a lack of appetite thus a decrease in food take so i lost weight as it is suppose to speed up your metabolism, but i found i had absolutely no energy on it and being a lightweight rower energy was vital but so was weight control so i stopped the 2nd day of my cluster migraines and noticed on coming off it a great deal of weight gain for a lightweight rower which was difficult and i am now unable to take any form of the pill :(
