To induce baby at 38 weeks

Hi, I am currently 37 weeks and 2 days. My baby weight as per 37 weeks ultrasound is 2.8kgs already. Recently, she’s like gaining 300g per week. Worried that I’m not be able to deliver her in normal delivery due to her weight gain. Her head circumference is 32cm at 37 weeks. Planning to ask my OB to induce her on my 38 weeks and 4days, also this is my birthday. Any advise from mummies who has the same experience. Appreciate any feedbacks. Thank you.
