IVF question: Why did I get a false positive on my HPT?

I had 5-day blasts transferred on 4/30. On Saturday 5/10, I secretly took an HPT and WHOA! it came up Big and Fat and Positive.





However, yesterday (5/13), the blood test from the doctor were Big Fat Negative. Extra sucky, no?





Here's my question. I had an HCG shot on 4/24 and my eggs were retrieved on 4/25 -- a forced ovulation, as it were. So my HPT would have been 14-15 dpo (or when AF would normally arrive).





Shouldn't that have been plenty of time for any residual HCG from the shot to have cleared out? Or is there something funky with the IVF shot regimen that caused the false positive?





Thanks in advance -- I appreciate any insight you may have.IVF question: Why did I get a false positive on my HPT?
Nothing is black and white, sounds like your body just took a lil longer to expel the HCG shot then usual (as frustrating as that may be) it happens, theres nothing set in stone saying it is always out of your system in 14 days. Sorry I know what IVFdoes to people, Keep the faith, it will happen.


all the best.





oh and just for a tidbit of info from a recent IVF/reproductive study (my step Aunt is a specialist in reproduction techniques etc and undergoing further studies to get to high places in the field), 82% of couples who don't have success with IVF fall pg naturally within 2 years after last attempt. That sure gave me hope when I needed it, and it was very true in my case.IVF question: Why did I get a false positive on my HPT?
I have not gone through this, but my understanding is that it can take two weeks for all of your trigger shots and other stuff to clear out, which is why they schedule your blood test the way that they do. I think any test taken before the blood test can still have skewed results.





Sorry, that must have been unbelievably frustrating.
