My period started at the age of 11. It was very regular and always heavy the age of 17 when i started to skip all food but water from mornings to 5.00/6.00pm for 30 days. The problem started after 30 days. My period became regular again from the age of 22 when i started taking Parlodel and Primolot untim i got tired of it at 27. Im 31 now,im not on any medication and have not been having my period. My Prolactin level is high now and progesterone is low.
