I had my last period on October 8 2011 and I have recently missed my period for 8 days now. I have had unprotected sex for almost 4 months now, everyday. I have been very nauseous on and off for the past couple days. My appetite has increased and my lower back has been hurting. I do not use birth control or anything. I keep having a little tingly sensation in my abdomen and my breasts are sore. Does it sound like I am pregnant?
