Anything is possible. You can get pregnant on birth control. So being off it a month..of course its possible.
Yes it is possible.

1/2 chance.
No; there are a few days around ovulation when a woman is most fertile, but it is possible to get pregnant on ANY day of the month
No. Two days is nothing. Think weeks, a month or more. Then, possible pregnant.
yes I've had a chemical pregnancy and been pregnant the following month.
no it's not possible to be pregnant for two years without giving birth, but sometimes very few women get to be pregnant for ten month and then give birth (it happens).
Yes, bleeding while pregnant is possible, though unlikely. You may want to speak with your doctor.
Yes, it is definitely in the higher range of days to get pregnant. For a woman to get pregnant, she needs to ovulate (release a mature egg from her ovaries). For most women, ovulation occurs about 14 days after her period. But it can vary from month to month and/or for each woman. So it is possible that 16 days after your period, that you could fall pregnant.
