Ladies with a BFP!!! Anything at 3 dpo?

katie β€’ Pregnant through IVF after 4 years of infertility and 4 consecutive early losses. Mommy to Alaina (6) and Niko due 11/18 πŸ’“
I'm very aware it's too early for pregnancy symptoms lol. I know implantation isnt until 6-12 dpo.. I'm just wondering has anyone had anything out of the ordinary at 3 dpo? Not necessarily pregnancy symptoms just anything that's different at 3 dpo before a bfp. TIA β˜ΊοΈπŸ’•
