Scared to be excited

Guys I’m so excited for this little babe. I’m over the moon. But this is my first pregnancy. I know my mother and one of my friends miscarried with their first pregnancy. I am so scared that it will happen to me. I know if it happens, there was nothing I did wrong. But gosh I keep picturing a nursery, baby names, and just my little family in general. I am so excited but I want to be realistic too. I’m 6w1d. I have had a lot of symptoms, but I’m currently cramping and that symptom scares me so bad. 😪 I just needed to vent. I know that I just need to try and relax and enjoy every moment. But I’m so scared of getting heartbroken. This is intense!!
