I just got my period 10/20/08.. & it is now 10/23/08. It seems to be ending, which is unusual. It was a bit heavy on the first day, & now is really light. I have been feeling tired, nausious, been quite hungry frequently & have also needed to use the restroom quite a bit, as well. Could there be a chance I'm pregnant & If there is, when would be the best time to take an at home test?
