Sorry me again...

Im starting to freak out! My cycles fluctuates between 27 and 28 days...im on cycle day 30 and no period. I NEVER miss it unless im pregnant! Shit is like clock work every month. I know something is off because i LOVE seafood and sushi and the thought is making me sick to my stomach. I dont want to tell anyone i know yet so this app is all i have. Im taking a test later. September just seems to be my month, i got pregnant with my daughter 3 years ago in september.
