Gravid Female/Gestation Period

I have a female Red Tail Boa that was returned to me after time with a male in January. She had been showing all signs of being gravid (the shed, the lack of appetite, the fat tail) and now in June, closing in on July, I'm curious what the chances are that she'd still have any babies. She recently ate a rabbit, but it had been several months since her last meal, and her tail is still bigger around than my calf.

From what I've read, the long term can be anywhere from 6 to 10 months depending on what website you visit, and we're creeping up on 7.

Anyone here have any advice?
