It takes ten lunar months for the pregnancy to go for delivery. That is forty weeks. The duration of the menstrual cycle is of one lunar month in most of the women. This duration is counted from the last menstrual period. It is counted for nine months and seven days ahead of last menstrual date on the calender.

No, as not all Dog's come into heat every six months exactly. Some may have a heat cycle eight or nine months after the last one. Smaller breeds usually have their heats slightly further apart than larger breeds. Also, some breeds of Dog, such as the Basenji, only have one heat cycle a year so it is nothing to worry about.
Not smart, you are playing with fire. Need to complete the cycle of pills to be sure they are effective.
