I had my last period on dec. 29, 2010 and I have a normal 28 day cycle and still haven t had a period or any indication that it s coming on soon. I then had sex on jan. 6, 2011 with a guy then had sex on jan. 14, 2011 with another guy and i ve been sleeping a lot more, the smell of food and certain things make me feel sick, my breast have been tender around the nipples, and my stomach feels different. Could I be pregnant? and if so who is more like to be the father?
