This is why, at room temperature, iodine, which has the largest molecule, is a solid, bromine, which is the next in line in terms of size, is a liquid, and fluorine and chlorine, the smallest of the molecules, are both gases. So remember, nonpolar molecules only exhibit weak London dispersion forces.
For most women, the length of time between ovulation (when an egg is released from the ovary) and their monthly period is between 12 to 16 days (this is called the luteal phase). The first day of your menstrual cycle is the first day of your period (day 1). The period usually then lasts anything from 3 to 7 days.
