Pains on left side

Rikki • TTC our rainbow after a miscarriage in September.
So for the past couple of days I have been having cramping and I asked my doctor if it was normal and she said yes. Well today I have had some sharp pains on my left lower side. Now they are quick and sharp nothing to have me doubled over in pain and no bleeding but it concerns me. I am 5 weeks 5 days and have my first ultrasoun scheduled for the 30th. Does anyone have any advice?
