What foods or anything can i take or do to jumpstart my period? i've heard of vitamin c and warm baths?

Wives' tales: To my knowledge, there's nothing save for hormones that can provoke a period. If vitamin c and warm baths provoked period, we would likely use that over hormones, like progesterone. If you want greater control over your period, best is to take a birth control pill. With that you can skip a period by taking the last week of placebo pills. Best of luck!
