If you are pregnant, sometimes it does that, Have you been sleeping with someone lately?
it varies by person, we are all unique

I'm not sure what the doctor will do about it but I've been told that not having your period at 15 1/2 is rather normal as a girl can get her period at any age between 8 and 16
Its totally normal i have had the implant and haven't had a period for two and a half years but every month i get the cramps, bloating and other symptoms
Should be normal for you. Mine was normal, it took a while for it to return though, and even longer for me to start ovulating again.
Yes it is very normal to feel it in the stomach, you must remember you have completed half the period in months of your pregnancy.
It seems like a lot, but it's really half a cup.
Yes perfectly normal. This is called the "break through bleed" which basically means (in your case) it's the first period you've had since coming off BCP.
