I agree with busymom about the psychic. I am sorry this has made you fearful.
To make you feel better though, I think every women who wants to be pregant and thinks she might be has those same fears. I remember with both of my girls being positive I was and then wondering if I was just making myself feel that way. I remember being fearful to take a test because then I would be so diappointed if I wasn't. When you finally find out you are, you will think why was I worried. I anxiuosly looking forward to knowing you are.
