If there is a male cat nearby that is intact and not able to get to her physically, the heat can last longer. Estrus lasts from 4-6 days if she mates, and up to 10 days if she doesn't. It can reoccur about every two weeks.
I have had 2 female cats from kittens, and from my experience, they usually come into heat anywhere from 6-8 months. Usually in late winter, early spring is the first time. From that time, they can go into heat every couple of months. My outdoor female once had 3 litters in one year.
