Positive thoughts please!

I'm about 6 weeks pregnant and have had on and off spotting for 2 weeks. Mostly it's been brown, but I've had 2 days in the last 10 days that it's been red, and mild cramps every once in a while. I've had blood tests and an ultrasound and  so far everything's been fine. I woke up at 3 am and had sorta heavy red spotting- no clots, no cramps. I went in for more blood work today and have an ultrasound tomorrow. I'm nervous and I know there's nothing I can do either way, just trying to stay relaxed and positive. Positive thoughts please!
