I need some advice

So I’m a 4’10” girl I’m 38 weeks pregnant and haven’t dilated. My doctor said only a fingertip. I feel like they are scaring me into getting a c-section if I reach 40 weeks claiming that my baby will be “too big” for me to push, however they haven’t even done another ultrasound to confirm that. My last ultrasound with them was at 35 weeks and she was weighing 5lb 10oz. I did an ultrasound today with one of those ultrasound places and she’s only weighing 6lb 10oz at 38 weeks! I feel like they are trying to rush things. They also have asked me to induce at 39 weeks and 3 days. I’m scared inducing as well because what if my body doesn’t end up dilating due to me being induced. At first I agreed with them on inducing, but after doing research and reading up on it I just feel like it’s better if I wait till 40 weeks and then if I HAVE to be induced then obviously I will but then there they go saying I might need a c section if I get to 40 weeks. So my question is, can I refuse all these things there telling me??? What can I tell them at my next appointment?
