A week late

I am now 1 week late. We're TTC and I just get the baby blues when I see that BFN. Should I test again? We're just so ready for our BFP! For a little over a week now I've had spazzms and throbbing sensations in my breasts. They don't feel bigger, but I have a small chest (tmi). Also, today I went out to lunch with my office, Mexican, and almost puked. I didn't but I felt extremely neasous. I went to the doctor and tested and it also came back negative. What should I do? Any advice would help me so much! Thanks ladies!
