I missed my birth control pill twice around the time I would be ovulating, a week and a half ago.

I have been very fatigued the past several days.

I've noticed the past 3 days I have been making trips to the bathroom about once every hour. I am not drinking an increase in water. Today, I think I have gone to the bathroom 10 times!

I have no other symptoms, as of yet.

What causes increased urination, if I am in fact pregnant?
