Blood clots first trimester?

Jessica ♡

I’m 7w1d today and I’ve been spotting for about a week now, light cramps and brown/red blood. I had a blood clot today and I’m wondering if that could be normal? I’m in absolutely no pain. I had a miscarriage July 2017 and I had huge blood clots and severe crippling pain with it. It doesn’t feel like before. I feel confident about this baby. I have an ultrasound appointment on May 7th. Opinions please? I’m trying to keep positive and not stress too much. I attached a picture of my 6 week ultrasound I got done April 23rd. I had been spotting for 3 days before the ultrasound.
