So..

I'm not sure if I'm pregnant or not. It's too early for me to take a home pregnancy test. I'll give a run down of a couple of dates.

October 23-First day of my last period
November 1-extremely aching boobs. Swollen and very very very tender
November 3-Extreme nausea

My period isn't due until Thursday the 20.

All my "symptoms":
Swollen/tender breast
nausea
nausea that gets better once I eat
extremely tired 24/7
Kind of moody
bloating
stuffy nose
headache
frequent urination

I'm not sure if they are all related or what. but I pretty much feel like crap. The big thing though is that I'm on birth control. My boyfriend does ejaculate inside me. So that's what is making me wonder if I'm pregnant. Can someone PLEASE tell me what they think
