1st Trimester Anxiety

Hey moms/ moms to be, I need some advice. I am about four weeks into my pregnancy and my body seems to be doing well as far as I can tell. I’ve been have mild on and off symptoms and my pregnancy tests have been consistently dark. I went to get some blood drawn today to check my hcg level and I just can’t stop worrying. I had a chemical pregnancy last month and while I am very greatful that I am pregnant again and it seems to be going well, I just can’t shake the what ifs. Why if it happens again , what if I miscarry later on , what if the hcg levels gone down. It’s terrifying me because this is so important to me 🌈 anyone know how to deal with this ?
