It could be ovulation, but if they have only been breeding for a month, there is a good chance that it wasn't. Is she still eating? If she eats now, then that's a definite no. How long was she fat? Ovulation doesn't happen over a few minutes then go away just as quick, it occurs over a day or two. As far as the shower goes, why do you think your BPs like it?

Are you looking for palpating advice?
