Worries

I'm 6 weeks 3 days today and I just can't help the feeling that I'll have a miscarriage again. I'm so worried about it. I've talked to my hubby about it as we're both worried but something this morning is just making me think somethings wrong again. I've booked in to have a reassurance scan in two weeks. I really hope my little rainbow sticks this time. Does anyone else feel like this? 😢
