Panic and doubt

I've spent the entire week expecting to get my period. I must go to the bathroom 50 times a day, each time certain that I will see blood, and each time...nothing. It's so hard for me to believe this, I guess it's because I want it so badly.
In my first pregnancy it was rare to have one day with no spotting. This time I have everyday with no spotting. It's just unbelieveable. When will I stop doubting my body?
