"Addicted" to testing!

Since I'm three days late. Which does happen for me I always feel the need to take a hpt. I've peed three times already this morning so if I test now and it's negative I won't believe it. I'll think "oh well it's not the first urine" or "its too early" or "bloodwork does show my levels run on the low side."
Anyone else ever do this? Maybe I just want to be pregnant so badly. I don't know.
