I am not sure when it actually started, but on Friday I took her to my moms because we were going out of town. I don't keep a diaper on her at home anymore, so I put one on her when I got to my moms.
Well she was walking funny so I took it off to adjust it. On her pad was a few dark brown spots.

I thought maybe I missed it and it was at the end of her cycle. Well needless to say when I picked her up my mom said she is definately in heat. I haven't checked her yet so I don't know how red it is or if it even matters.
Is there something I should be doing for her? She does still have the diaper on. She is acting ok, nothing out of the ordinary. She is 9 months old. She will be 10 months on the 21st of September.
