Cats have a different kind of cycle than humans. They come "in heat" or "in season" in spring and autumn of every year and this is characterized by being more vocal, and acting friendlier than usual by rubbing up against the furniture, etc. They get a slightly bloody discharge, left for unknowable owners to clean off of the kitchen floor and family sofa.

No. Menopause is the period when women stop menstruating, and since cats do not menstruate in the first place, they cannot go through menopause. Only primates, such as humans and chimps, menstruate. (Cats will bleed a little while in heat, but this is part of the estrous cycle, which is not the same. Estrus in cats is closer to the period right after menstruation in humans.) They don't even go through menopause in the sense of ceasing to experience estrus; cats remain fertile throughout life.
If you menstruate then you're not pregnant - it is possible to bleed while pregnant, but it is biologically impossible to menstruate while pregnant. The very earliest you can tell when you're pregnant or not is 3 weeks after you had sex, via pregnancy test.
