I just got two Madagascar Hissing Cockroaches, one male and one female. They were purchased together in the same container, and I am not sure how long they were together in the container. I now have them separate, but was wondering how long it would be until I know the female is pregnant or not. I understand the gestation period is roughly 60 days, but are there any earlier indicators that she might be pregant? How long until I can be sure she either is or isnt?
