I'm 17. For the last few months I got my periods regularly. But there was no regular bleeding in October.Towards the end of October I got my periods and it has almost been 3 weeks since the bleeding began.There is heavy flow.This is the second time that my period is lasting for more than 7 days. I'm quite worried about this.Is this normal among girls of my age?
Thankfully your flow does not double when you skip a period.
First missing a period and then bleeding for more than 3 weeks is a good sign that you need to speak to your doctor, nurse or clinic. It can be just a hormonal imbalance, or something else. But only your doctor can do the tests to determine what is going on.
