hcg levels and ectopic pregnancy

Hi,

I found out that I was pregnant 7th may (approx 5weeks gone) had a hCG blood test on the 11th of may and it came back at 1500 I had them repeated 48 hours later and they were 2100 another 48 hours late I was told they had dropped a little and its not a viable pregnancy. I was sent for a scan and told that the could be something in my womb but its more and likely a cyst but there looks like there is something in or around my left ovary as well as some fluid that may or may not be blood which is pointing to ectopic pregnancy. However, I have had no pain and no bleeding and was discharged. Now surly if there was a change of it being ectopic they would do something about there and then? Now i am having to wait another 48 hours and they are going to repeat the blood test again. but where is the point of that?? i now feel like im going crazy as i still feel pregnant and with no bleeding or pain im unsure what to think! This will be my 3rd failed pregnancy and the hospital don't seem to be in any sort of rush to see what the hell is wrong with me!
