I've been off of birth control for almost four months now. My periods have been regular for the most part. Unfortunately, me and my husband haven't got lucky yet :( I was supposed to be ovulating on the 15th of November. We had unprotected sex and he did it inside. Is there a chance I could be pregnant? We're trying so hard :( how long until I will experience symptoms? Or is it possible to know if I am by December 10?
