Why have my periods changed from 28 day cycle to 32? im had one day of heavier bleeding and now it's really light? my periods are normal. i'm 27

Your periods are: normal and your cycles are regular. Reproductive hormones can't count or tell time. Minor variations in the cycle length are common & normal. Heavier bleeding in the beginning of your period & lighter bleeding at the end is common & normal as well. VERY heavy and/or painful periods & pain or discharge between periods AREN'T not normal & require medical attention. Best wishes. Dr. Anne.
