Keep the male with her at least until she goes into shed. She could just be showing signs of a "pre-ovulation swell" which would mean she hasn't actually ovulated yet. Pre-ovulation swelling doesn't always = ovulation, but it's a GREAT sign. It can last for months before ovulation so your male may still have quite a task on his hands... err... spurs 
Also, if she does go into shed, it'll take longer than normal. Around a full 2 to almost 3 weeks from the day she ovulates.
Good luck and keep that male in!!
