Same food, same workouts, same sleep. Then, five days before your period, your belly swells, your face rounds out and the scale jumps three pounds. A week later it is gone. You did not do anything wrong. Your hormones did it.
What happens the week before your period
After ovulation, progesterone rises. It tells your body to hold on to water and it slows your digestion. Then, right before your period, both estrogen and progesterone drop fast, which can make retention and cravings worse for a day or two. The result: water in your face, hands and belly, plus more gas from food that moves through you slower. Both at once, which is why period bloat feels bigger than any other kind.
The signs it is hormonal
- It shows up on the same days each cycle, usually three to seven days before bleeding
- Breasts feel full or tender at the same time
- You crave salt and sugar, which add to the water
- It eases within a day or two of your period starting
What helps during that week
- Keep salt steady. Cravings push you toward chips and takeout, exactly when your body is already holding water.
- Keep moving, lighter. Walking, cycling and stretching keep water out of your legs and gas moving through your gut.
- Protect your sleep. Short nights that week make retention and cravings worse.
- Potassium and water. Bananas, spinach, beans and a steady water intake help balance the salt.
- Magnesium, at a real dose. In a two-cycle study, women taking magnesium had less premenstrual fluid retention than women on placebo by the second cycle (Walker et al., 1998). Citrate and bisglycinate are the well-absorbed forms; oxide is the cheap one.
- Help digestion along. Ginger sped up stomach emptying in a 2008 study (Wu et al., 2008), and digestive enzymes reduced belly distension after a meal versus placebo (Martin-Biggers et al., 2024).
- Take the edge off stress. Stress and PMS feed each other. Ashwagandha root extract lowered stress scores by 33% over 90 days versus 4% on placebo (Gopukumar et al., 2021).
Why starting early matters
Most of these actives work over weeks, not hours. The magnesium study saw the difference in the second cycle, not the first. That is why a daily routine beats a rescue pill the night your jeans stop closing.
Where Ebb fits
Ebb Daily De·Puff is built for exactly this week: dandelion leaf and magnesium (citrate plus bisglycinate, 150 mg) for the water, enzymes, ginger, PHGG fiber and a spore probiotic for the slower digestion, ashwagandha, L-theanine and saffron for the stress and the mood.† One scoop every morning, all cycle long, so the week before your period is just another week. Every dose and study is on the Ingredients page, and the full logic on Why Ebb.
When to see a doctor
Bloating with severe pain, very heavy or irregular periods, or swelling that lasts all month is worth a conversation with your doctor. Conditions like PCOS, endometriosis and thyroid issues can hide behind "just PMS".
