Filter conditions ## Most read Menstrual cycle The luteal phase: what's happening in your body and mood - The luteal phase runs from ovulation to your period, usually 11 to 17 days. - Progesterone rises then drops sharply in the final days if you're not pregnant, and that can affect mood, sleep and appetite. - For most women the dip is mild and short. For some, it builds into a pattern that looks like PMDD. Read Condition PMDD (premenstrual dysphoric disorder), explained PMDD, premenstrual dysphoric disorder, is a diagnosis for severe mood and physical symptoms that show up in the week before your period and ease within days of it starting. It's rarer than PMS and comes from how your brain reacts to normal hormone shifts, not from having abnormal hormone levels. A doctor confirms it with daily symptom tracking over at least two cycles. Read Condition What is PMS? Premenstrual syndrome, explained PMS stands for premenstrual syndrome, the physical and emotional symptoms that show up in the one to two weeks before your period and ease once it starts. It's driven by the normal drop in estrogen and progesterone after ovulation. PMS differs from PMDD, a more severe diagnosis confirmed with daily symptom tracking. Read PMS or pregnant PMS or pregnant? How to tell PMS vs pregnancy symptoms apart PMS and early pregnancy share tender breasts, bloating, fatigue and mood swings because both run on rising progesterone after ovulation. Spotting, nausea that doesn't ease, and a missed period lean more toward pregnancy. A urine test is most reliable from the day your period is due. Read Condition guide PME: when your period makes another condition worse PME means premenstrual exacerbation: an existing condition like depression, anxiety, ADHD or bipolar disorder gets worse before your period but doesn't fully go away afterward. That's different from PMDD, where new symptoms largely clear up once bleeding starts. Daily symptom tracking over two cycles is how you and a doctor tell the two apart. Read PMS vs pregnancy Premenstrual cramps or pregnancy cramps: how to tell Cramping alone can't tell you PMS from pregnancy, since both often start in the days after ovulation. PMS cramps build with your usual pattern and ease once your period starts. Pregnancy cramps, when they happen, tend to be milder, don't resolve into a period, and are confirmed by a test, not by how they feel.
