These are my notes on Rose's last breeding ('07/'08). I also have notes from my '06/'07 season in there but they weren't NEARLY as detailed. You can see I saw her swelling multiple times in the last season. I posted a picture timeline one time and you can see the same thing in that post.
A curious thing about this last season is that I didn't expect to breed her, but then I looked in towards the end of February and her body weight looked great, so I dropped the temps and gave it a try! 
Hope this helps!

Fed a small meal on 3/23/08 and reintoduced on 3/25/08
Aligned with tail waiving and saw sperm on Rose's side - Rose began to move her tail abruptly and Mr. I held on like he was attached although I didn't see copulation - 3/29/08
