Hi, im new to pregnancy and have never experienced it before, how ever I think I an having early pregancy symptoms. I had unprotected sex on the 14th of Feb and it is now the 23rd, and I have been feeling slightly nauseas, had mild back pain, dizzy occasionally, mild headaches and im awfully tired. My period isnt due till about the 10 -15th of march but I was experiencing period like cramps today and I found I have a little bit of discharge in my undies and when I wipe. I would be greatful if you could get back to me on this as I am extreamely worried. Thanks :s
