POS on kenyan sand

[Spat]

Hello,
my male kenyan has breed my female the last month.
I think I saw the ovulation but I'm not sure, because my female is really big! So, now she is more slim than this time.
I think I saw this ovulation around the first week of april.
The problem is that she doesn't have post ovulation shed.
But, she refuse to eat since two week, and before, she doesn't refuse a meal!
What do you think about this?

Thanks
Spat
