AF is suppose to arrive OCT-17 now me and my husband have been trying for three months now. Last night I woke up with a horrible headache to the point I couldn't pick my head up and I was in tears. Now this mornin I feel super sick to my stomach very bad hot flashes and to the point I threw up. Not sure if these are the early signs of pregnancy or if I'm getting sick. Is itto early to even get signs?
