one month
Bella found out she might be pregnant around six days after her wedding.
17 days I think
Bella tells Edward her period is 5 days late and Edward discovers it by himself.
No one knows for sure but I estimate 1 month exactly. In chapter 7 she finds out she is pregnant and has been since the wedding which was seventeen days ago. In chapter 8 it mentions that Bella had been back in Forks for 7 days (one week) which altogether makes 24 days. Add another week for Jacob protecting Bella and that makes 1 month! Possible more....
Bella does not get pregnant in New Moon. She gets pregnant in Breaking Dawn but... Bella figures out she pregnant in chapter 7, but Edward gets Bella pregnant in the chapter called isle Esme.
Bella does in get pregnant is The Twilight Saga: Eclipse.
