Its 40 days after shed and still no eggs...

[Stewart_Reptiles]

moreover in 33 day she started to shed and in 39 she shed.

I am not understanding this part at all but I will make a general comment.

IF she is indeed gravid and it has been 40 days since pre-lay shed you should be able to clearly see the eggs moving when holding her head up, tail down.

40 days is not abnormal either is she is indeed gravid, while eggs are laid on average 27 to 35 days after pre-lay shed it might take longer. (I have a female that just laid 49 days after her pre-lay shed)

Now the real question is, was it a pre-lay shed and is your female really gravid?

Again the timeline

Ovulation
14 days after ovulation pre-lay shed
27-35 days after pre-lay shed egg laying

Again this is an average and it can be more or it can be less.
