What you said is how is goes most of the time . However we had a female that after Ov all she did was soak up until her prepay shed then she started the heat seeking. But right after her Ov every day all day she would be in her water dish. But she's gravid and fat and due on the 16th. But to the OP everyone has pretty much said it all. Just watch them for Ov keep pairing until the female refuses the male. If you happen to miss her Ov then that's kinda a last sign that she may be gravid. That's not a for sure sign but if you see that then watch for a shed. But you should be able to tell when she's building and even after Ov they are fat... Lol they will look thicker and wider at the tail .... Hope this helps. If you have any more questions just ask. Good luck
