i’m pregnant so i’m going to have to get it drawn quite a few times. i got it drawn yesterday and i had a vasovagal syncope (had very jerky involuntary movement and blacked out bc of not enough oxygen to brain) and it freaked me out BAD. i have had blood drawn before and i was perfectly ok but i guess they took too much from me at once yesterday and that happened. can i prevent that from happening again? and can i deny any future blood tests (besides the glucose test)? ugh i’m not recovered from what happened and i feel very weak still. thank you in advance
