For those of you who started blood thinners during pregnancy when did you start ?

Merry Christmas everyone !

I am 9 dpo and got 2 possible vvvvfl on 2 different tests , I am scheduled for a beta in 3 days , however I am worried maybe I should already start doing my injections, its xmass and my vvvvfl are so faint tat I really don’t want to bother my obgyn cause its so early !

I had 2 miscarriages that’s why I’m testing so early and as you can imagine I am super worried.
