Getting pregnant after a miscarriage

Laura
I have a question for everyone. I started bleeding august 1st then I had a miscarriage at exactly 5 weeks, on the 3rd. I bled till the 7th or 8th. It wasn't painful, just like a heavy period with some clots. I went and got my blood tested 4 days after bleeding and my hcg levels were back to a 0. I know that the dr said it could take up to 6 weeks to get a period. I'm usually regular but I know my body could still be messed up. IF I was back to my normal schedule I would have started august 30th, I still haven't started nor do I have any signs either. When should I take a test? I don't want to take it early and then get disappointed! This was my first pregnancy! Please give some advice.
