worried about another ectopic

I'm a mom to 2 angel babies and one handsome little boy. I lost my last baby 4 weeks ago and now I'm 3 days late. I know I ovulated from temping and OPKs. I'm just concerned because with 2 of my babies I had a positive pregnancy test before AF was due but with my ectopic I didn't get one until I was a week late. I don't think I can handle another ectopic. I would almost prefer AF shows up so I don't have to worry about it. I'm just looking for a little support and positive words.
