I faint everytime I get my blood drawn and get severe anxiety days leading up to having to get it done!

Well I have to get the 3 hour glucose test on Saturday to rule out gestational diabetes! I failed the 1 hour test two weeks ago (by only 4 points) and now having to do the 3 hour blood test.

I thought the 3 hour just meant you drink the drink and they draw your blood 3 hours later, but I just found out it means they draw your blood when you first get there, and then every hour on the hour, 4 times in one day!

How can I prevent myself from fainting each time?! :( any tips for overcoming the fear of blood draws? I’m pregnant and already had tons of blood taken but I get so worked up and faint every time! I don’t want to react like this each time. How do I stay calm and not faint ?!
