Anxiety about delivery. Due in 4 days.

I'm a FTM and I'm due in 4 days, I have my (hopefully) last appointment in 2 days. Last appointment I wasn't dilated at all, but I was 50% effaced.

A few nurses have mentioned when they measure me that I look very big, but my doctors haven't said anything about it. Last appointment my nurse asked my birth weight. I was 7lbs 14oz, my boyfriend was 9lbs 4oz. I am a very small person (5ft even and 110lbs before pregnancy) however, my boyfriend is 6ft 6 and like 240lbs. I called and asked for an ultrasound but they insisted if there hasn't been any issues it's not necessary.

I'm worried that I will go past my due date (which is Sept 27th, I won't be induced until Oct 4th) and he will end up too big for a vaginal birth. I know they want to avoid induction but I kinda thought maybe if he seemed to be big they could induce me sooner instead of waiting until he's so big that I have to have a C section.

I'm not sure any of this really makes logical sense. I'm just very worried my doctors aren't taking my anxiety about this seriously. I feel like they ignore my concerns about this. I would totally be fine with going with the flow and waiting for him to come on his own time, even if he is huge, if they could give me some reasoning and ease my mind.

I'm not even looking forward to giving birth, I've been laying around for days because I'm just not ready. It makes me so upset because I see all these women trying to induce labor because they are so ready, but I'm so terrified and anxious I feel like I'm avoiding it.

I have a lot of anxiety when it comes to pain and hoping my baby is healthy. I'm not sure what this post is even asking, I just need some words of wisdom. Because honestly I'm freaking out.
