Question: I'm almost 13 and I haven't got my period yet and all my friends a the same weight and height as me and they got there's when they were 9 is that normal?
Dr. Farah Kroman: The date of your initial period can’t be known however there seems to be some genetic link so ask your mum when she got her period as you might get yours around the same time. Usually girls get their first period at around 12-13 years old but the age range can vary from 11-16 years. If you have started developing in other ways (e.g. breasts or pubic hair) then your period will usually start within 12 months of this happening.
