Just back from the OB and I feel like a boss. I had my blood drawn (4 tubes) from the back of my hand to reduce chances of passing out but I was so scared my blood stopped flowing to my hand after two tubes an the nurse had to switch the needle to the other hand. in the second hand she couldn't find a vein so she moved the needle in my skin till she found it and I didn't pass out! right after I went to my OB appointment and that went good only gained a pound. I'm so tiny !
