Natural birth or c section

So I need help my 1st baby was 7.2 and I had a hard labour my 2nd baby was 7.10 and got stuck in almost broke his collarbone and almost got nerve damage after my 2nd born they told me I can't have a baby bigger than 7 pounds I am pregnant with my 3rd baby I am have 6 more weeks and they told me that it's my choice if I do C section or have a natural birth since mother's intuition is better than measuring a baby through ultrasound. So now I'm freaking out because I don't wanna make the wrong choice... help
