Hi guest, I tested on day 10 after my first day 3 transfer. I used discovery and got a pos result straight away but i had two embys on board and both implanted which would be why I got a pos straight away.
I had another day 3 transfer last month and tested the day before bloodtest and got a bfn (used discovery again) my bloods came back negative.
I am having another day3 transfer tomorrow and will probably home test again the day before my bloodtest, I find this helps me prepare for the outcome from the clinic. Good luck and remember to try to treat yourself during your long anxious wait, hope you get a BFP!!
