Why has my cycle changed from 28 days to 30?

Why cycles vary You may still notice changes from time to time. The length of your cycle depends on your hormones, which can fluctuate due to factors like diet, stress, jet lag, working night shifts, exercise, or taking an emergency contraception pill (the morning-after pill) (11-18).

Why did my period go from 28 days to 31 days?

Longer cycles are caused by a lack of regular ovulation. During a normal cycle, it is the fall of progesterone that brings upon bleeding. If a follicle does not mature and ovulate, progesterone is never released and the lining of the uterus continues to build in response to estrogen.
