I am on my first period?

for your first few periods,yes.they will be irregular for a bit of time as your body is just ajusting and getting used to it.sometimes you may miss it ,it may start again after youve already had one and its very unlikely to start at the same time every month.this may happen for as long as 2 years but is very unlikely.it will at least take 6 months.

it is normal for most periods you might find that tomorrow you dont have a period anymore it tends to be your body expelling the last bit of blood ..

the only way i can describe it is to think of a shampoo bottle you use it until its empty but if you left it cap down for a day all the remnants will eventually slide towards the lid so you have a little more to use ... so its just getting rid of the bits its missed

This can be normal for any period in my experience, it can also happen after having a bath I've found. Keep an eye on it though, if it keeps starting and stopping see you GP, you may have a hormone imbalance. I have to control mine with pills.

Totally Normal. Nothing to worry about will last from 5 to 7 days.

Yes it's normal. Don't worry :)
