question: Hi My name is Nikole and I am 20 years old. I am having serve lower adominal pain. My Last Period was on Spet.21st.2011 and I am ovulating according to the Ovulation Calculator:   Based on your answers, you're likely to be most fertile from Sunday, October 2, 2011 to Friday, October 7, 2011. If you were to get pregnant during that time, your due date would be Wednesday, June 27, 2012.  So with that all said, Do you think I should go to the doctors to check my self out? I am in so much pain I think its a UTI but I dont know. Please Reply to me.
