12 weeks ultrasound tomorrow - need reassurance!

I have my 12 weeks ultrasound tomorrow. Had a great ultrasound at 7w4d but haven’t had anything since.

I had very small pink spotting when wiping once after a BM at 10 weeks (Minimal spotting like size of a penny - pink mixed in mucus). But no spotting before or since.

Need some reassurance I’m nervous this very minor vaginal spotting could be a miscarriage.
