ok so the Вампиры are meant to have no blood because they have no сердце right. but bella and edward have sex which doesnt make any sense so how can they do it

No No No. Вампиры are full of blood, of course. I mean, they live off of it (animal или human). They have hearts, but they've stopped beating. And they have sex because they still have human desires. They're just suppressed by thirst. Meanwhile, if Ты mean...how is Renesmee produced, the answer is in Breaking Dawn. Every human function is still the same for male vampires, just as humans. Male bodies don't change much..and because Edward was Холодное сердце at the age of 17, he had all the right parts to make a baby. Bella was a human..a changing female. Ergo, she had all the "working" parts to produce and carry a baby.
