Should i go or not? HELP

Eunice • 19 years old ☺️ 1st baby 🙈 due February 28, 2016 with a girl 🎀👶🏼🍼 follow me on IG @hieuniceishere ☺️
So i found out that i'm pregnant and it says that i'm 5 weeks pregnant but i haven't went to the doctor or anything but everything is fine. Should i still go see a doctor just incase or should i wait ?
