Spotting

Gina • Ttc baby #1!
Do any of you spot a little in the morning? It's not a ton but it's there.. Like browny.. I am not really sure how far along I am.. 7 weeks by lmp bug yesterday I had an ultrasound and they put me at 5.5 weeks.. The spotting is scaring me.. It's the second day in a row.. Just want to know if others have or have had the same thing...
