I'm a 17 year old girl and have had my period for about 5 and a half years (ever since I was 11), and it's always been pretty regular. Typically, it only lasts 5-6 days, and usually comes on time. However, this time, it came over 2 weeks early, and has been going on for 13 days so far. It's pretty light, but now I'm just worried and not sure what I should do. Please help!
And there hasn't been any change in stress, exercise, or diet, so I don't know what made it change like this. Help! I'm really freaking out now and I have midterms next week, and I really hope my period stops soon so I'll stop worrying.

You should see a gyno to put your mind at ease.

You shouldn't worry yourself during midterm week :)

Yea. Definatley see a gyno to get it looked at. It could be nothing but it may be something. Only a couple ways to find out. Good Luck!
