HI Dutchie,
Wow, what a lot you are dealing with. Congrats on being so persistent and informed.
Regards to taking Asprin for 24-48 hours from FET - it will take around 5 days for the Asprin to be effective in your system for blood thinning. We were always told to cease it 5 days prior to
DS surgery and when I had an amnio with this
pg my
OB didnt think there was enough risk of a bleed to even stop my Asprin at all (I did so ceased it 5 days prior).
I wish you luck with this cycle!
