I began a plant-based way of eating about two months ago. My period didn't come last month, so when it came roaring back this month, I honestly thought it was just making up for lost time. My period is usually a maximum of four days, the first and second days being the heaviest, so I was thinking that even with it making up for missing last month, I shouldn't be still flowing like day one or two after four days. Then, I remembered something. When I had frequent afib episodes, my doctor prescribed Xarelto, a blood thinner. It made my period longer and I even had to stop taking it once so my period would actually stop. I'm thinking I'll have to do this in this case because my body is functioning in the exact same way. This is problematic because I'm also anemic. I'll skip my dose today and tomorrow, if necessary. If anyone's interested, I'll report back to let you know what happened. All said, I'm taking Doctor's Best Natto Sera and it's done wonders for my BP. I'm happy to get back on it when my flow stops. I think it's also worth saying that Serrapeptase should probably be halted before dental work and major surgery, as well.
