hi sharon, i am pretty sure i heard you have to wait at leat 7-10 days after your pregnyl shot to get an honest test. you are better to wait until the blood test. i did a preg test last aug when i was doign my first IVF and had the pregnyl shot. i got a positive home preg test, but blood test showed non- viable pregnancy. it was high enough to give a reading but not high enough to be pregnant.

so even though it is hard to wait, you may save yourself some heartache...
hope this helps. sorry to be blunt!
