First prenatal appointment tomorrow....advice?

MJ • Married 5.25.13 💍💙 Expecting baby #1 September 5th 2018 🤰🏼

I have my first prenatal appointment tomorrow and I'm so scared. I feel like I should be so excited but I'm scared there is something wrong with the baby ( no reason to think this) or the doc will be mad about my weight I'm 268 but I have lost 20lbs since December and work with a trainer three times a week. Any advice or what should I expect? Thanks for helping my anxiety ladies!
