A girl can dream, right?

I was supposed to get my period today. I had a dream last night that I was pregnant. It was pretty detailed, and when I woke up this morning, I thought it had to be true. All the symptoms I've been having seemed to add up, and I ran to the bathroom to take a test. Negative. All day, I have been going to the bathroom to check, and I still haven't gotten my period. I am never late, so I still feel like I could be pregnant. I've been having what feel like period cramps all day, and I don't know what to think of it. I just don't want to wake up tomorrow and have my period. I'm so anxious, and I just really want to be pregnant.
