Numbers (Beta)

Well, today did not go exactly as I had hoped.  When my results finally came online, they were much lower than I was expecting.  I was with clients all afternoon, so the clinic left me a message basically, saying that my numbers were lower than they were hoping, and they want me to go back and test again in 3 days.

So, here's the shot from my screen (sorry for the quality):

As you can see, my levels today (day 31 of my cycle, just over 4 weeks) are 132.  According to this chart, that is a bit low.  However, I have checked other beta charts online and it's not uncommon to have numbers this low at the beginning.  In fact, 132 still matches the criteria for 4 weeks on a number of charts.  So I really don't know what to think now!

DH did a bunch of reading up on it (how sweet) and says we have to wait till the next test to see if the numbers are going up or down, and how much they are going up if they are.  There's not much information you can get just from one beta.  I have found a lot of success stories, starting with low betas.  But it also can mean miscarriage, or ectopic pregnancy (which has been a fear of mine this whole cycle).  DH thinks that since a BFP appeared today on tests that it wasn't showing on a few days ago, that means the levels must be going up.  Hehe!  He also hung out with a friend today who told him that last night he had a dream about DH talking with our son!  Prophetic maybe?

Anyone have any tips or advice for me?  Waiting 3 more days is going to be killer!
