Fingers crossed for you there
It is all a bit confusing really as alot of the signs some people look for like bowl wrapping , laying inverted etc also happen with non gravid females too and depending on who you talk to they all have a different set of events they look for.
The ones that seem constant though is the Ovy and Pre-lay shed.(please correct me if im wrong)
I think they like to trick us sometimes with these little teasers of bowl wrapping etc
