Not too likely.
But we never say never! You are just going to have to wait and see, and of course get b.c. if you aren't planning on being pregnant.

Of course there's a chance. Any time you have sex there's a chance.

You'll have to wait and see. If you don't get pregnant this month, don't get discouraged, just keep doing what you're doing and you'll be pregnant in no time. :)
