I've been on my period for 3 weeks as of today. The blood flow has increased over the past 3 days. I've only been experiencing periods for a little over 6 months, as I am 14, and I don't know what this means!!!
Irregular periods in the beginning of getting your period is normal. However in six months of pretty regular periods to a three week period, maybe you want to see your doctor or pediatrician. Just to make sure... Or see what they say. Have you mentioned to your mom or parents?
No, I've been afraid to see what they say. My longest period before this was 8 days. Actually I didn't have a period at all in October, and this started Nov. 27th.
