Hey Rich! Is that the female you got from me? She's looking good. I have her "sister" breeding with a sunglow this year also. I was told they're not related when I got them, but the same breeder produced them and they're both the same age.
Have you taken the male out yet, or is he still in there with her? I'm just asking because it looks like that might be a pre-ovulation and not the actual ovulation. Happened to me last year and I pulled the male out not realizing the girl didn't ovulate yet and then she gave me slugs. The pre-ovulation is more of a wider swelling and the actual ovulation is taller.
Here is a girl that I don't have anymore. These pictures are all her, 2 different years breeding.
Here, she never actually ovulated, but she gave me a really big pre-ov swell:
It's very wide like the picture of your girl looks.
And here she is the year before with a nice ovulation. You can see how much taller it looks:
Hope this helps. I could be wrong, but your girl looks like the pre-ov and if you take the male out she may slug on you. Best of luck to you!!
