Sorry to hear that. 5 days after transfer sounds very early. I had 2 IVFs before and my Doctor did not do blood test untill 10 days after transfer. Wait few more days and do HPT. or you can request blood test again after few days. Good luck. I hope to hear good news from you.
I agree it sounds way too early. I had my transfer the past Sat. and dont go back for a Beta till next Wednesday. Wishing you luck
