Implantation bleeding

Did anyone NOT get implantation bleeding and find out they were pregnant? I’m in the two week wait and currently nearing the end of the implantation window. There’s been no bleeding. I’ve been wearing a pantyliner to make sure but nope nada! Im pretty sure Ive not missed it so wondering if it’s possible to not bleed at all when it implants or if to give up hope for this cycle (IUI) and prepare myself for a negative. I have sore breasts but that could just be pms. Thanks ladies x
