Scare of miscarriage


Hi, I'm after some advice, this is my first pregnancy I'm 8 weeks, I've never been pregnant before so no miscarriages etc, but I'm just so scared of having a miscarriage I'm scared that even everyday things will cause it and it's really starting to get me down, Ive got morning sickness, nauseous and mild cramping, no bleeding or anything, I don't know how to stop panicking ??
