Did my IVF on 08/29/08...supposed to do blood test in two days (09/10/0

...couldn't wait and did HPT this morning. It says positive! So, this is the first time I've tested at home (did 4 IUI cycles in past - 3 failed, 1 miscarried, this if first IVF) and I don't want to have false hope. I did NOT have a HCG booster, only on progesterone in oil and del estrogen so from what I understand, it should be accurate - right? Only if it came back negative would I not rely on it - right?
