Torn about genetic screening

I’m a first time mom and currently 14 weeks. I have no idea if I should do the genetic screening. I worry about everything so I feel like if I get the screening I am going to be even more stressed out. The only ultrasound I’ve had is my 9 week one and it looked good. I’m only 20 years old and have no family history so my doctor said I’m low risk. My boyfriends dad is adopted so we don’t know much about his family. I’m worried about false positives and unnecessary stress. However I’m scared I’ll regret not getting it done. What did y’all do??

Thank you 💕
