my aunty also has it, so does my mum, thankfully i have not tested postive for it,

my aunty had a still born boy found out at 34 weeks, she only found out she had factor 5 ledian and thrombophilia once they tested lots on bubs, thankfully she got pregnant a yar later with a girl who is now 9yrs old, but she went threw alot needles and all sorts of checking to get her, she had several misscarriages later and got hubby to get snip so they didnt have to go threw it anymore

my mum only just found out she has it (she smokes and has all sorts of probs and a few mild strokes and only now just got tested for it she is 51) she has 3 kids , me my broher 32, and my other brother boy 15, and she didnt have any dramas or no anything while pregnant, although older brother was born premmmie, and younger brother not sure but he was tiny and healthy, and me the biggest baby she had,

i have heard some people say its a problem when your pregnant with a boy for some reason they think, i dont no if true but alot of people in my family have only lost boys.

sorry if im no help

my aunty only got the injections once she got pregnant, soon as you find out your pregnat is when u need the blood thinners and what not to help stick better as far as i no, my aunty only got it all once she found out, so she was charting so your dr may be right, its only high risk once your pregnant so they wont do anything untill your pregnant
