My numbers are going up...

Ok so I started cramping last night and my sugar 155. And I was have bad headaches. They did u/s in and out.. And blood work, and a pap... So she said at 5 weeks they couldn't see anything but that was normal, but the uterus showed signs on pregnancy.... And last Wednesday I had my blood drawn and my hcg levels were only 112 , last night they were over 930... And she is sending me Thursday morning for another drawing..
