I have been sick for the last two weeks which is basically around that time I last had sex. Any little smell makes me feel nauseous, I don't feel like eating and well I love my food. I have been getting headaches and slight dizziness. And some discomfort in my lower abdomen. I also have been sleeping more then usual and my breasts have been sensitive. I have had my time of the month but it was a week early. Could I be pregnant?
