OK I had a 30 cycle.. oct has one more day then last month. When will I ovulate.. will it stay the same?

You generally ovulate so many days before your period. Check out Fertility Awareness to learn to know the signs that you are ovulating.

General rule of thumb is that you will most likely ovulate about 12-16 days before the next period is due regardless of how long your cycle is. This is only a starting place however. Some women will naturally ovulate a little sooner or later as their norm... and when trying to become pregnant, a day can make a world of difference sometimes.
