Does frozen embryo takes longer to implant and produce HCG hormone?

When i did fresh embryo transfer day 5 i had implantation bleeding on 6dpt and 5dpt it was more like a spotting, then i got my BFP at 9dpt

(Unfortunately lost the baby at 4w4d)

Now I transferred 2 frozen embryos day 5 at May 3rd, no spotting just mild cramps from 4-5dpt until now I’m 8dpt, I tested today and got a very very very faint line that I’m not sure of what it is, my beta test will be on May 13th

I’m a little bit worried that I didn’t get implantation spotting this time do you think it matters?
