When to call the doctor

Lauren • Happily married and mama to my little girl
I am 5 days late & ttc. I have a few symptoms such as nausea, tiredness, light pelvic cramps and more frequent urination. How late should I be to call my doctor? I'm getting negative results, and I don't want to feel stupid if the doctors comes back negative also. AF is neve late for me. Any advice would be great :)
