Kinda freakin' out

I'm not sure what's going on with my body... I have a lot of signs of possible pregnancy, but I don't really think I am. I don't really want to be pregnant at this point in my life, but if I am, I will love my child with all of my heart! For the last 2 weeks, I've had nausea, headaches, backaches- like I get with my period (my uterus is pointed a little back and thus causes a lot of lower back pain over my period), sore boobs, and my husband says I've had lots of mood swings...poor guy! He thinks for sure that I'm pregnant, but I'm almost wondering if it could be my bc? I had most of these signs when I started the pill but that was over a year ago, so I'm not sure what's going on. I did take a pregnancy test yesterday, and it showed negative, but it's a little early. I stopped taking the pill a week early, so I should get my period tomorrow or Thursday... But I think I hafta wait to get a correct reading on a hpt until my "normal" period which would be next week...I dont really like this waiting game at all!
