I have one daughter who is almost 2. And when I was pregnant with her I didn't find out until I was almost 3 months. Well me and my husband have been trying for a few months. I had my last period October 25, 2013. Well according to my ovulation calendar my schedule ovulation was November 8,2013. Me and my husband had sex November 1, 2, 4 and 7th. I have been having mild cramps and backaches. I also am very tired. Could I be pregnant?!
