They have to be old enough to have periods, but apart from that they can get pregnant just about anytime. The chances of becoming pregnant varies with where they're at in their cycle, but bodies aren't clockwork perfect so there aren't really any "safe" days.
No you only produce eggs during your menstrual cycle
A lady may be fertile at any time during her menstrual cycle. That the lady is more fertile at some times during that cycle is true.

The estrous cycle occurs in most mammals, including dogs and cats, and is typically shorter and more predictable than the menstrual cycle in humans.

They are entirely related. The previous answer that it's ultimately "God's will" and science is only "sort of" involved in fertility is complete nonsense; the entire menstrual process explains in detail when and how fertility occur. In other words, depending on where in your menstrual cycle you are, you will be more or less likely to become pregnant (less likely during your period and just after, more likely during ovulation).
There is nothing dangerous during the menstrual cycle, if you mean when a woman can get pregnant then it depends on her cycle - the only way to know when a woman is fertile or not would be to use fertility awareness method.

The key difference between the menstrual cycle and the estrous cycle is that the menstrual cycle occurs in humans and some primates, while the estrous cycle occurs in most other mammals. In the menstrual cycle, females have a monthly period of bleeding, while in the estrous cycle, females experience a period of sexual receptivity known as "heat" or "estrus." Additionally, in the menstrual cycle, females can conceive at any time during their cycle, while in the estrous cycle, females are only fertile during specific times when they are in estrus.
No, kissing your girlfriend and stimulating your girlfriends breasts has no relation to her menstrual cycle. The menstrual cycle is controlled by a domino effect of hormonal changes between her reproductive organs and her brain, kissing her has no impact on this cycle. Her period will come as normal in accordance to her menstrual cycle, the only time you can change this is if you were to have sex with her and get her pregnant.Oh, heavens, NO.
