I had a 4 cell emby transfered on saturday the 9th and the embryologist said it would take 3-4 days to implant.

I am currently on prgesterone and pregnyl so if i was to do a HPT it would more than likely show a positive, but this is only becuase of the pregnyl in my system.

I would wait until your beta test at the end of the 2WW, otherwise doing a test now will most probably just be giving you falso hope!!
