Hi, What not to eat when it's that time of the month, I have the best help for it and it is very helpful. When it's that time of the month you feel pain and have cramps and your mood changes, etc. The two first days is always hard and what is best to take is advil (ibuprofen) as needed and have plenty of juice such as orange juice and apple juice. Drinking orange juice or apple juice during your menstrual period makes you detox better and the more you go to the bathroom you will feel better. If you have major pain lie on your back not on your stomach or else you will feel more pain and keep a warm heating pad on it. Have like a cup of tea and have some rest will make you feel better.
