7 weeks pregnant anxious

I am 7 weeks tomorrow and so so anxious that I am going to miscarry again or what scares me most is a missed miscarriage. What if the baby has already stopped growing and I don’t know? It’s constantly on my mind. Doesn’t help that I have hardly any symptoms at all. Are there any signs at all of a missed miscarriage? Will there always be bleeding eventually?

I had a miscarriage in March which started with pink spotting, had a scan, saw heartbeat then I lost the baby the next morning! It petrifies me.
