Nervous

Tomorrow I will be exactly 6 weeks and I'm so nervous because I have absolutely no symptoms. Reading about miscarriages have scared me tremendously and idk how to shake the fear. Is it normal to have no symptoms at 6 weeks? My HCG level was around 1,000 on the 7th and on the 11th went up to above 4,000.... I'm not sure what it is now but I just don't have any symptoms. Occasionally sore breasts and my SO said I'm having terrible mood swings but I'm not hungry at all anymore and I'm no longer bloated. My first ultra sound isn't until next month on the 10th 😪
