Hi Yael - As everyone else has said - you're not 'supposed' to get any symptoms until after implantation, however I certainly believe that I had early pg symptoms, so it's not impossible!!! I started feeling really nausious and 'off' a few days after conception. After feeling that way for a week and noticing that my sense of smell had increased dramatically, I did a HPT that was negative. The next morning, I couldn't even eat breakfast - so I don't think it could have just been in my head. Ended up getting a really faint BFP two days later, so there you go!!! Funnily enough, a week after getting the BFP, all my symptoms disappeared and I haven't had any m/s since - very weird!!!

Good luck.
