I had made a request of my body last year to let me know a) when I was ovulating again and b) when I was preggers. With ovulation I had so much libido compared to the previous 2.5 years that I knew it was body communicating with me! Then, what I reckon was implantation, in January I experienced a horrendous day of pelvic pain that was barely walkable. I told DP it must be implantation. Symptoms eventually developed (not nausea this time) and I only went to the doctor for a test so that the doc could officially advise me not to turn out to fire calls anymore...otherwise, I would have kept going So, yep, the EDD the GP gave me was what I had calculated anyway and I knew I was pg, I just needed to hear someone tell me to stop turning out to fire calls.
