Hey lovely I don't want to be the voice of doom and I really hope you are pregnant but I think you should read the info below, I had a friend who had her heart broken due to early testing .. I really really hope I am wrong xx
As much as you'd might be tempted to test on the ride home from your transfer, unfortunately you're going to have to wait. The ovulation "trigger" shot that you took prior to egg retrieval (or insemination, if you did an IUI) contains hCG; so if you test too soon, you'll pick up traces of the hCG trigger shot and not the hCG produced by a pregnancy. The dosage of the trigger shot usually varies between 5,000 to 20,000 I.U. of the drug; it comes in several brand names including Novarel, Ovidrel, Pregnyl, and Profasi. The hCG usually stays in your system 8 - 10 days after the trigger shot; this can vary depending on the dose given by your doctor and your body mass.
So you absolutely don't want test until at least 9 days after your trigger shot and realistically, it's nearly impossible to get a positive test until 11 days after your trigger. I beg of you - please don't make yourself crazy or sick with worry by testing too soon. Save your money on those extra HPTs and wait until at least 11 days after your trigger shot to do a HPT.
