Shepard’s purse.

Anyone try the herb Shepard’s purse before? I have been doing research on how to stop prolong periods. I have been menstruating for 36 days now and really want it to stop. I have an appointment with a gynecologist but due to crappie insurance the doctors aren’t great and all the ones I got in contact with are booked until at least July. I want to try a something at home to help stop it. Anyone have any suggestions?
