Cautiously Excited About a BFP!

I tested this morning with one of my Walmart specials, an Equate Brand HPT (picked up after my dollar store fiasco).  IT WAS POSITIVE! I am so nervous though.  I don't want to get too excited because I know there are so many things that could happen.  I know I am at increased risk of miscarriage since I have PCOS.  Again, a wonderful side effect of PCOS.  I am going to test again tomrrow and Tuesday then my beta is Wednesday.  If my beta is positive, my doc will order a repeat beta, probably 2 days later to confirm.  Beta's should continue to rise the further into the pregnancy you go.  If the numbers (level of HCG hormone in my blood) start to fall, that means you are going to miscarriage.
