IVF 10,000IU HCG HPT?

I also took 10,000IU of hcg before IVF and took a pregnancy test everyday after my retrieval to test out and trigger. I did a 5 day transfer. Tested trigger out by 8dpo and at 9dpo it started getting darker and triggers DO NOT get darker. So I got a positive 4 days after my 5 transfer so it's definitely possible but the only way to know for sure if it you tested out your trigger. I know the doctors suggest not testing on your own because it adds stress but I had to know before I went in and had them tell me! GOOD LUCK, I say keep testing, it's the only thing I looked forward to during this horrible waiting period!
