Last month I had my reqular period. It started on August 10th and lasted the same amount of time it usually does. Nothing abnormal about it what so ever. This month I have yet to get my period. I am not sure if it is pregnancy, but me and my fiance have unprotected sex alot. I have a pretty stress free life at the moment, so i have already ruled stress out as being the reason why. Ive had the munchies lately, it seems that i am always hungry. I've woken up with a sore throat the past 2-3 mornings, and this morning i coughed up blood when i was clearing my throat. Could this be pregnancy? And when should i take a home pregnancy test? I really dont know what to think at this point. Any advice would be much appreciated.
