Never experienced implantation bleeding

Has anybody else never experienced implantation bleeding?

I’m 7-8 dpo and still praying every time I go pee that I see something that would indicate implantation has occurred

I have near grown children with my ex husband and never experienced implantation bleeding in my early 20’s

Now I’m almost 40 and same thing

I have had 2 back to back early miscarriages since November and never had implantation bleeding

I’m just feeling hopeless today and I’m out this month

Just looking for a sign and it isn’t happening 😞
