TELL ME IF I'M CRAZY FOR THIS IDEA

I'm finding that the anxiety of waiting on my first prenatal visit is really getting bad. I just want to know if the baby is growing or if this is going to be another disappointment, so I had the idea of going to the ER just so I can get a blood test and ultrasound. I have been having mild cramping and seeing as this is my 3rd pregnancy this year I don't think it will hurt to go...... am I crazy lol?
