I did the ovulation calculator on web md and according to the last two menstrual cycles, I was at high fertility on 06/06/08-06/11/08, I ended up having sexual intercourse on 06/06/08 and 06/11/08 not planned by the way... I thought nothing of until my breast started getting very tendered and heavy and then I just recently started getting very sensitive to smells and getting very nauseous. Could it be possible to have symptoms of pregnancy so soon? According to web md I'm due for my next cycle on 06/25/08. Is it too soon to take a pregnancy test?
