Need Help, Sign of Ovulation

Hi all,
lets i introduce myself, im Keza, from Indonesia.

I have been pairing a couple of burmese from June until Now, I have also witnessed them mating for 4 times they were locking on 19/7/12, 06/8/12, 08/08/12 and 18/08/12, and probably there are another not witnesed mating. the albino male is 2 years old, and the normal female is 3 years old,

The female shows different behavior, she reject to eat, hissing a lot and love to make perfect coiling, i also confuse she is fat or she is ovulating???
