Some questions about ovulation

[Dave86]

Hi guys, yesterday I found my female laying on the basking point:




Could it be an ovulation?
In the last week she's always been in the cool side of the tub, until yesterday.

I don't think she's ovulating, I've heard that once a female ovulates you can feel soft eggs through palpation...I feel big hard follicles.

So, what do you think? How many days until ovulation?
The last shed occurred on 10th April.
She's a 2000 gr '06 female and she's been bred to a '08 normal male (800 gr) 4 or 5 times from November to February...should I expect some slugs because the last copulation occurred almost three months ago?

Thanks

PS: by the way, there's a pic of them breeding:
