I suspect she'll just take longer to shed- make sure you keep up her humidity as well as the warmth- both digestion & shedding require GOOD hydration from the snake's body, & it's a challenge for them to do them simultaneously- it often takes much longer as a result. Feeding too close to a shed can cause a mid-shed regurgitation, or a shed in a zillion pieces (or they can get "stuck") when they finally get around to it. So as I said, just monitor warmth & humidity- don't handle her!- & hope she gets both done as planned. I wouldn't feed larges, btw. And especially not "back to back".
