Do you think the fact that I am getting PUPPS in this pregnancy too will make my Dr do the c-section earlier?

I had PUPPS (a crazy rash that you get usually in the last trimester cause your allergic to being prego) really bad with my daughter 2 years ago. It's very uncommon to get in later pregnancies but somehow not only did I manage to be one in the 10000 or whatever who get it the first time; I am not in the even more miniscule amount who get it also in later pregnancies; Yay me! Anyway she was too large for my body too get out and so although I have signed VBAC concent forms and would like to attempt it; I basically am a really small framed person (5' and 100lbs with very narrow hips) who has babies that although are deff average are too big for me (daughter was 8lbs 21"). So my Dr really doesn't like to do c-sections before 39 weeks, which is when I have one scheduled for (basically I figure if I go into labor by then great; if not I'm ok with that too). However since I noticed today that I am starting to get PUPPS again; do you think my Dr. will do it even earlier? I want to make sure my baby is healthy and ready to be born, however I can't take care of a 2.5 YO and live with PUPPS again. If you've never gone through it you can't understand; but if you have/known someone who has I know you understand why I say it. I literally used to lay in room temp oatmeal bath water for 30 mins at a time like every 2 hours. I went through like 50 tubes of cortizone cream and uncountable bottles of lotion. Thankfully it was summer and I was home alone so I got away with walking around in a maternity bikini. But now it's cold so that won't fly. I am freaking out like I was suffering from a good bit of depression and anxiety ect last time due to the dicomfort. ANyone who's happened to have it twice and ALSO a c-section think he'll be sympathetic to me?
