Beta hcg levels....please help me my heart is broken...and im in limbo?

So I had emergency exploratory laparascopy surgery this past weekend because I went to the ER with abd pain. My LMP was Dec 25th. I don't know exactly how far along I am because I ovulate later than day 14. Its more like day 22. Neways I went in to the ER they said I had an ectopic pregnancy. After the surgery the dr said there was no ectopic pregnancy. THey did an ultrasound and said they could not determine the yolk sac or whatever. So neways I went to the operating room. They did not do a D&C or nething like that. So neways on sat @ 2 am my beta hcg was around 3000. I had more blood work yesterday and it was almost 5000. My dr said that he isn't going to bank anything on these numbers until friday because he has been tricked by these numbers before. So in any event I need to kno if I was going to lose my baby wouldn't the numbers be droppng after the surgery. I know that the numbers didn't double. Ohh im just so confused and I don't know what to think. I know that I have to wait until thursday for more blood work but I would just really like to know what I am dealing with here. My hubby and I REALLY want this baby. Its heartbreaking to me that we might lose it. Also my dr said that he doesn't care that they didn't see a yolk sac because its so early thats why he hates when they do the ultrasounds bc it causes so much anxiety early on. So please someone tell me what they think about this whole thing...are my chances of having this baby good or bad? I just want to be prepared...Thanks so much!!! <3
