waiting for results

I went to take a blood test yesterday to see if I  am pregnant. It has been just over a day and I AM FREAKING OUT. I really didn't want to tell my boyfriend that I thought I was pregnant, I was scared he would think I was just being paranoid and crazy...
 
But I'm still sick to my stomach, I've been unable to keep anything down for awhile now and all I can think of is spicy carnitas. Even if this test is negative I still really believe I'm pregnant. I'm so scared. What if I miscarry? All day I've been blocking these bad thoughts and trying to think positive but it's so hard when I feel like there is so much at stake here. I wish my doctor would call me back already!
