So about 1-2 weeks before I found out I was pregnant I had a dream that I was. Everyone told me it doesn't mean anything but boom I was

Well I'm now 3 1/2 (6weeks based on the first day of my last period) and last night I had a dream that I miscarried. It makes me nervous ... I know I shouldn't do that. Everyone tells me not to stress but it's hard not to be a little scared. My sister has had a few miscarriages before having my niece do that kinda makes me think as well.
