I know what you mean about the smell becoming worse during your menstrual cycle. I have a fecal odor and I never smell myself until I get my period. Then all the sudden I can smell it very strongly throughout the day until my period ends. I have struggled with constipation all my life. About 4 years ago I started having lots of gas with the constipation and since then I have had a fecal odor. I also have the feeling of warmth in my colon and since people have been cured with a flaxseed mixture I tried that. It doesn't seem to do anything for my constipation. I'm really disappointed because I had a colonic appointment and had to miss it so I will try to reschedule soon. Can you tell me more about your other symptoms besides the odor? Have you always had constipation or gas? Maybe we can work together to find a solution. If constipation is a problem you may want to try apple cider vinegar as well. I am going to try that soon to see if it helps me go. Let me know what some of your other symptoms are when you get the chance and hang in there! We'll be ok. We just have to figure out what works for our bodies because everyone is different.
