Tranexamic acid
"I took Lysteda 2 pills 3x a day for 5 days and my period was much lighter.  Extremely lighter.  But then I got another period for another 5 days after no flow for 4 days and now I am having a third period this month. They are all lighter and more manageable but who wants to bleed for 15  days of the month.  I am planning to try it again next month to see if my body just needed to get use to it but this month wasn't what I was expecting."
