hcg level low, to early for ultrasound?

[jhopeful]

So my husband and I have been trying to conceive a child for over two years.  After 6 failed IUI's and 2 IVF's...Our third IVF cycle I got pregnant!  We thought we could be all excited that finally we were pregnant!! But No!  The doctor is concerned by my "sluggish" hcg levels.  on 10/27 it was 73 on 10/29 it was 120, 11/2 it was 371 and 11/5 it was 686.  Now up until this last test, I was still optimistic!  Everywhere that I read it says doubling every 48-72 hours, which it pretty much was. Then this one it didn't!  The doctor is all concerned because their idea of "normal" is every 48 hours. After almost two years they should realize I am not a NORMAL patient.  Is this something that I should be concerned about?  It is going up! I am going in on Monday 11/9 for bloodwork, ultrasound and to speak to the doctor.  Do you think it's to early to see anything on an ultrasound? I am so scared!  I just more than anything to have a baby and thought this was finally it!

I had low levels with my son (following a molar pregnancy) and the nurse told me "it doesn't look good."  Needless to say I was terrified!  Well, 7 mos later he was born a healthy 8lb15oz bouncing baby boy.  No complications or anything.  Good luck to you and happy baby-growing!

Thank you Steph! It is nice to hear that other people have had similar experience and have had healthy pregnancies!  I went for my first ultrasound yesterday. and while the levels are still "slower" they are rising.  We saw the gest sac yesteday and the yolk.  Hopefully next week we will see the fetal pole!  =)
