You should be avoiding caffeine during your period, since it can make you anxious and retain water, so kick that coffee addiction and replace it with tea. Different types of tea can help with different symptoms. For example, green tea can help with cramps, while peppermint tea can soothe an upset stomach.
Stay away from foods with caffeine which help increase cramps and blood floows, Things such as coffee , soda , etc. And also stay away from Fat foods with a lot of greaze and oils ( hamburgers, etc) which can also make your periods worse.
