My Ball Python roxy was laying on her side today for about 5 minutes,Noting TOO dramatic, just laying slightly to the left (eh, right?) this is the first time ive seen her do this......when females are gravid dont they do this ?

That cant be a reason because she has not been bred (or around any males whatso ever) so im pretty clueless, what could this be, ill let you know if i see her do it again.....
