Ectopic??

I'm 4w6d today. I went in yesterday because I've been having abdominal cramps, bad lower back pain, nausea, vomiting, and diarrhea. They did an ultrasound but said it was too early to determine anything. However, I did see the tech write "gest sacs?" (As in more than one....?!?! Trying not to think too much into it)
My HcG level was 3270. I'm having it rechecked tomorrow. Did anyone else have these symptoms so early? And what were your HcG levels at this stage??
Edit: they did an ultrasound so early because they were suspecting an ectopic pregnancy, hence the topic title. This is my second pregnancy and a lot of my abdominal pain is on one side. They said with the HcG level being fairly high (but still within normal range) they cannot rule out an ectopic pregnancy.
