Mild cramping with spotting

SE

Hi I am5 weeks pregnant as from today a few weeks ago I was spotting brown, and this morning I had a tiny bit but again it's gone, I have mild cramping in my hips, phoned the dr last week and she said to ring her when I'm 6 weeks for a scan, I'm going out of my mind thinking I'm going to come onto my period, had this happened to anyone before ? Any advice would help, 😞
