Hcg levels

CJ

I had my hcg checked on the 17th of December they was at 28 then again on the 23rd they was 137 then again on the 30th they was 1651 or 10651 i can't remember. But on the 30th i had a scan and they saw absolutely nothing. I got told once hcg was at 1500 they should be able to see something so they are assuming its an ectopic and ive got a scan again in 5 days. I'm a wreck!
