Not many symptoms?

Lizzie • Due in July 2019 with our rainbow after a loss on 6-28-18. Blessed with a 2.5 year old, 7 year old and 13 year old. All boys

I am 5 weeks pregnant, this is my third pregnancy. I have a 2.5 year old son and had a miscarriage back in June around 7.5 weeks. Both times I didn’t have major symptoms I don’t think other than fatigue and a little bit of tenderness in my breasts but this time around so far I don’t have many symptoms either. Is this okay? I am just obviously super nervous about everything since my miscarriage over the summer. My first ultrasound isn’t until nov 28.
