All I do is worry lol

I need to semi vent here. I miscarried early last month. I found out two weeks ago I'm pregnant again. Now I'm just afraid of it happening again. I'm excited but every twinge an cramp has me worrying I'm going to lose this pregnancy. I've checked my cervix it's closed An soft, I have numerous good pregnancy symptoms.. headaches, sore boobs, twinges, ect. But the cramping.. it's been so on and off for like four days? No bleeding. Not extreme but it's there and it's annoying because it makes me worry and then it makes me feel like I'm worrying too much. Is this much cramping normal.. I'm around 5-6 weeks
