Whats my baby chance of coming early?

Chanel🎀 • 20 years old🎉 expecting baby #1 due july 11th 🚼 engaged 💍👰🏾
I haven't gone to the doctor yet for my first trimester my apt is dec 16. My big question is what the chance of my baby coming prematurely if i came prematurely? Or does that not effect my baby?
