On the small amount of information given, assuming you had sex, then YES.

I'm sorry for the misunderstanding... can you delect my account because I don't want any emails to my account if its possible. I would appreciate it.. thanks

I would appreciate if you can delete my account... sorry for the misunderstanding.. thanks

Um.. seriously? If you have had sex in September (or late aug).. then yes. Go get a self test kit.
Actually.. skip that and go right to the doctor!

Unless you are on one of those newer birth controls that reduces the number of periods...

We NEVER delete accounts, simply stop using it.
