Im starting to get a little concerned

Okay, so I'm going to try to make this as short as I can, and probably fail miserably. In the beginning of my pregnancy, my due date was moved back just under 2 weeks. The ultrasounds that my ob office uses is old as dirt. The conception date they gave me was only 6 days before I had a positive test. Not impossible but very unlikely and it wouldn't have been a crazy dark line like I had. At my anatomy scan I measured just under two weeks ahead of the new due date, which would put me back at the original one. They said the early scans are most accurate but with the machine being as old as it is, testing positive at a time where most people wouldn't, and now measuring exactly to the day of my old due date, I kind of doubted that in the back of my mind. Well I had an ultrasound done again two weeks ago. Guess who's baby is measuring over two weeks ahead. Her estimated weight was 7lb 2oz. This is at 35 and a half weeks. Now granted this can be off by 10% but even then, she's still a big baby. Today at my appointment I measured at 41 weeks... nobody is even slightly concerned... That's three weeks ahead now. My son measured right the whole time, he was still a 9lb 1oz baby, so I know my body can handle big babies but at some point it's going to get dangerous I feel like. I asked about induction and he said after 39 weeks, which I understand. I straight told him that I understand it does put me at a slight risk of csection but at this point, her being as big as she is puts me at in increased risk. At 40 weeks she will reach the 5000 gram mark if she grows on track. Oh and I'm on day 5 of early labor too, that's probably worth mentioning. I just honestly feel like if she doesn't come very soon something bad could happen. I want her to stay in as long as she can, but is the extra week of lung development worth the increased risk that come with 10lb+ babies. ? Idk if I'm overthinking everything but I just can't shake all these feeling.
