I don't think I had any symptoms yet at 3 dpt. Plus, I actually had less symptoms after my IVF (which was successful) than I did in my two previous pregnancies (which were natural pregnancies that ended in miscarriages). Only real symptom I had early on was mild cramping, and that started a few days before my beta test. Breasts were just barely tender, while they had been extremely sore the two previous pregnancies. By the way, I was also 35 when I had my IVF. Best of luck with everything!
