Anyone had spotting or bleeding in 1st trimester?

Beth
I'm about 6 weeks along but I've spotted the whole time. I didn't even know I was pregnant until this week because I never missed my period. I had an ultrasound and lab work today that im I'm waiting on. I'm just wondering if anyone else has had spotting or bleeding that's not ended up as a miscarriage. I dont have severe cramps or anything.
