How long to show?

Helen • I am 30 yrs old. Been with my partner 5yrs. He is a guitar teacher and I am a home carer. Bought our first house last year. Now have our first child. A son named Harvey born 27/10/3016
I am currently just over 5 weeks gone and I still don't have anything showing. I understand that it can take a while for a bump to appear so I wanted to ask. How long did it take for your baby bump to appear and how sudden dis it appear? Post pics if you want stating how far gone.
