pregnant after loss and I'm stressing

I miscarried back in March. I was 6 weeks and 5 days when I started to bleed, but at 5 weeks 5 days I started to spot and went for bloodwork my hcg level came back at 214 which was low they said, and wanted me to wait a week to retest. the morning I was to retest is the morning I woke up bleeding I went to the e.r instead of repeating and my numbers were 94 by the time I left there I had already passed the baby. I am now 5 weeks and 4 days pregnant. I feel like I'm actually pregnant with this baby sore nipples and all day sickness, but some days my nipples don't hurt as bad which stressed me out. I think once I make it to my first appointment which is the 29th I'll be okay cause I will be like 7 weeks and 3 days and farther them I made it with my last. but for the next 2 weeks I guess I'll be stressing out. my husband doesn't really want to talk about it with me because he's scared if he gets too excited we will lose this baby too. I did tell my best friend, but she doesn't know what to say as she has never lost a baby. just worrying and I know that's not going to help but I just don't know if I can handle losing another baby
