Nothing shows up until levels are over 900 so by the next week something will show
It is most likely an ectopic pregnancy and the embryo is still too small to be seen by an ultrasound. At that HCG level, your uterus lining should have thickened by now and made changes to prepare for the baby. If it has not done this, it is usually ectopic. I just went through this myself a couple weeks ago. In fact, your situation sounds identical to mine. Do not wait to get treatment for this. You don't want your tube to rupture. It can be life threatening to you.
I just had this happen. I am 4-5 weeks and had a vaginal ultrasound and nothing showed. The ultrasound specialist, radiologist, er dr and an obgyn all told me that's normal around this time. I went back for bloodwork the next day and my HCG levels doubled. Good Luck. =) They have my "official" ultrasound scheduled at about 10 weeks.

Ozone layer is depleting. The levels of ozone are falling.
No; by the time the sac is visible on ultrasound, there would be detectable levels of Hcg in the blood and urine.
Blood work cannot tell you how far along you are as the levels vary so much from pregnancy to pregnancy, go with the ultrasound.
5-6 weeks, ultrasound machine quality and technician experience have alot to do with it also, if you are having your hcg levels checked between 1000 and 2000 is typically when the pregnancy is visible

It is called a transvaginal ultrasound. A new pregnancy typically cannot be visualized until the HCG levels reach between 4,000-5,000. This is when the gestational sac, fetal pole and yolk sac can be visualized. Cardiac activity is typically not seen on an ultrasound until 6 to 7 weeks gestation.
