To get periods early, some natural methods that may help include:

• Drinking herbal teas made from parsley, ginger, yarrow, rosemary, or sage, which are believed to stimulate the uterus and promote blood flow in the pelvic area.
• Having an orgasm or sexual intercourse, as the contractions and hormones released may help bring on periods earlier.
• Engaging in light exercise or gentle yoga to increase blood flow and reduce stress, but avoiding intense or excessive workouts that can delay periods.
• Applying heat to the lower belly to relax muscles and improve circulation.
• Eating certain foods like papaya, pineapple, vitamin C-rich fruits (oranges, kiwis, lemons), and spices (ginger, turmeric) which might support hormonal balance and uterine contractions.

It's important to note that these methods are not guaranteed and should be done safely, avoiding use if pregnant or with medical concerns. Consulting a healthcare provider is advisable if there are persistent irregularities or concerns about menstrual health.
