It will depend on the the female since they can store the sperm for up to a year or so I heard.

example i been seeing locks with my het pieds since OCt and the females just did her prelay shed( i hope lol ) 16 days after another shed and i am on that countdown of 27 days till she drops,should call nightmare since i had to all but seal the tubs to keep the humidity up ( dang electric heat)..

I also got a pastel ( recently) that i tossed in with a female and they been gonig for a long time but I guessing she already gravid she in a darken stage of preshed look.
