Not pooping!

Hi! i don't really use reddit but i've been browsing this sub a lot since i got my snake for tips and info so i made a throwaway account just for this question!

So i have a 13 month old BP who hasn't pooped for about 1.5 months ish and im getting a little worried, last time she pooped was about the last shed cycle and i've heard a lot of them hold it in until shed but is 1.5-2 months safe for them??

She eats adult mice every 14 days and is at healthy weight altho i think i should go over to rats soon since she's still growing pretty fast, she doesn't show any hunger behavior and is calm when handled as usual. she has a two hides at the cold side one moss humidity box that sits a bit colder at 23 degrees celsius, and one regular hide at ~26 celsius, one hide at the warm side at ~29-30 celsius and a decent gradient between the hides. ambient temp is also about 26-26.5 and humidity at 65-70%

but as said she's behaving calmly like always and i cant feel any lumps, she also passed urine about a week back so i don't think she's constipated (can they be constipated and still pass urine?)

​

sorry for the messy post i'm not all that used to reddit but thanks for all the good info from the sub i've gotten while luriking!
