Hi, Thanks for posting in HCM. I understand your concern. Unfortunately, there is no stopping of the flow once the process has started. There are medications like ibuprofen which can slow it down and ease the cramps, but there is no way that it would stop the period outright. You just have to understand that you can’t get rid of your period, even if you just don’t want to go through the issues for a couple of days. It’s a reality that must be accepted. Doing exercise, taking Vitamin C, drinking herbal tea, drinking good quantity of water, intake of gelatin and consuming foods like pumpkin, papaya, peaches, apricots, carrots, spinach could possibly play a role in shortening the duration of your period. Hope the information provided would be helpful. All the best.
