Ectopic Pregnancy or..?

Leann
I need some help..
For the past 5 weeks I've been experiencing severe pain on the right side of my abdominal/pelvics, and at first it was just dull regular cramping and slight vomiting for a few days and occasionally every now and then, but for the past 2 1/2 weeks I've been spotting but lately it's getting heavy then nothing then spotting then nothing then heavy again, and now the pain is so bad I can't move and I have to just stay still and they are constant. My boobs have also been sore and almost severely painful for the past 5 weeks as well.  The pain lately has spread to my whole lower abdominal and my lower back and I don't know how much more I can take. 
And I don't know if it has anything to do with the fact that even though I'm freezing, I'm sweating like dripping sweat. 
I'm only 16 and I'm scared... And I also don't know if I posted this in the right group I'm sorry.
