Natasha (2 years ago):

I am currently on 7.5mg coumadin, female, age 31. I had a stroke 1 mo before my 30th birthday. They know it was from a clot but they have no clue where the clot originated from. Here the last 4-5 months when I have my period, I am blind for about 10-15 minutes on my first day. Is this something I should be concerned about. I only take coumadin, so the only difference is my period starting.
