I'm 29 years old and I have never had a normal menstral cycle. My periods can be anywhere from 3 weeks late to 3 months late. They just come and go whenever they want to..and usually when they do come the cramps and bleeding is awful. I've also noticed that my hair has been thinning out as well especially over the last 10 years and I just wondered if my horomones could be out of wack...maybe perhaps causing the irregular cycles and the hair loss. I'm always told its normal..but it just don't feel normal to me.
