I am pretty sure my female ovulated the beginning of march and she just shed on about march 23rd. I think it was her pre lay shed which puts her at about April 20th. Question is if you hold a gravid female verticle which probably isn't a great idea will she still have a bulge in the lower stomach or is that only building. My female has a bulge but when just sitting in her tub she looks kind of normal but I noticed I could see her spine more today.
