Sorry for the late response (I have been away for a few days). I can't say for sure what my early signs were really as I also went down with a cold so my exhaustions was 10 fold. Around implantation time I felt like I needed to pee all the time when I didn't, towards 8dpo I was exhausted (but added to that was the cold), I am breastfeeding my 1 yr old once a day but my boobs felt like they were in the let down reflex constantly. But the main thing was my husband noticed a real change in my mood, as he said he's seen me pregnany twice before and the moodiness happened then, so he knew about 10 days before I did!!!
