am I out for not having symptoms @ 3/4dpo?

I just read on the "countdown to pregnancy" website that a lot of ppl have symptoms from 3dpo.
Sympyoms include like an increase of cm- which I don't have
Tender breasts - which I don't have
The only noticeable thing I DO have is an uncomfortable cramping sensation in my uterus 😞
Anyone else that didn't have any symptoms at 4dpo and still got their bfp?
