Light pink blood

Hello, I am 8 weeks and 5 days .. I would normally start my period this week I noticed light pink bleeding after peeing not last night but the night before I then made a doctor appointment for yesterday where she did a pelvic exam said things looked normal besides a yeast infection and told me watch it closely .. Had no bleeding at all yesterday and this morning after peeing I had a little more light pink bleeding .. But since has stopped .. I have an ultrasound tomorrow but I am still freaking out .. Anybody else have anything like this ? Should I be concerned ? Prayers for my poor little bean would be greatly appreciated
