Do I have anything to worry about?

Hey guys, so I just found out I’m about 6 weeks pregnant.. I’ve yet to see a doctor. honestly I don’t consider myself “plus sized” at all... but according to BMI charts I’m right on the line of overweight and obese. I only weigh 154 pounds but I’m 5’1. I wear a size 8, my body looks a normal weight pretty much but I’m still worried because I’ve read a lot of things saying my BMI could cause problems for me or the baby. Should I have anything to worry about? Or any tips?
