That is actually not uncommon. Activities which are out of the ordinary or stressful, whether it be school camp or exams or upheaval at home can often cause your period to come early if you are not on the pill. It is also a prime time for a first period too.
There difference is really minimal. Stressful times can advance menstruation usually by no more than a week. It would have been coming..just might have taken a few more days had camp not been there!
Thats the stage before menustration I believe
Discharge means that your uterus is cleaning itself, and getting ready to receive a new egg. If you see discharge, it means you period might come in a few days to a few weeks.
Not necicerily. Discharge can happen 1-2 YEARS before you get your period. Days and weeks I think are inncorect. Ask Bell Sprout. I think bell sprout said your period can (or usually) starts 1-2 years after discharge. Anyhoo, bell sprout will know.
Discharge is sticky, clear/white/yellowish (depends on the individual) stuff that tends to turn up in your underwear in small amounts. The discharge's primary function is to clean, lubricate and prevent infection in the vagina. This starts 1-2 years before the onset of menstruation and stops when menopause occurs.
Yes they do!
Breast growth is all part of the development process. Just know that you are growing! 
Are there any concerns that you have?yeah,is there like sizes in between in girls cuz I am not a certain size
Are you referring to bra sizes???
It also provides an example or two! thanxAre you referring to bra sizes???
If so there is an excellent site here: Getting the Right Bra
This site explains really well how to measure for your cup size and gives you a translation to what bra you will need to get. It has measurements for both Australia US& UK.
You find in most cases that there is a bra out there that will fit you. Sometimes it can be a little bit tricky depending on your shape though. Just have a shop around.
