Hcg rising too fast now?

Madeline

I did my initial quantitative tests. They did quite double, but went up to 280 something. Now a week later they are 5,700 and something. Now they think it could be in my tube. Can't anything just go smoothly? If it was ectopic wouldn't I be cramping? I stopped a few days ago. No bleeding, hardly any cramping. Anybody have experience with ectopic pregnancies?
