I have missed my period. It usually comes on at the end of the previous month and continues for the first three days of the next month. It is MIA as of now. I have been trying to concieve for nearly 2-3 weeks now. I am not sure if I'm pregnant yet but I am showing several pregnancy symptoms such as fatigue, headaches, morning sickness with no vomiting, hunger that's more intense than ever before, and sore breast. Also my libido has increased. What is going on with me?? Please give me some directions as to what to do. I don't want to take a pregnancy test if only its going to come back negative.
