Mower, i can understand why you are worried but please try not to lose hope at this stage. I have had one successful pregnancy and 4 miscarriages but had symptoms of a threatened miscarriage with all of them. With dd I lost quite a lot of blood but heartbeat was detected at 7 weeks and she is now 8 years old! From my experiences and from what I have been told by the professionals at the EPU, you should only expect to see a sac at 5 weeks and the best way of telling whether the pregnancy is continuing at this stage is if your hcg levels double within a 48 hour period (which they have, i have just read you other thread) regardless of the initial level. HCG levels in pregnant women vary enormously from woman to woman, don't concentrate on the levels, just remember that they have doubled. Wishing you all the luck in the world and that your little beanie hangs on in there. Please keep us posted, MN is here for you, I know how anxious you must be
