I suspect that I am having this problem except the tumor or "tumors" are on the inside of the uterus. When I was pregnant with our daughter (she's 18 months old now) my doctor found one inside the uterus. It was a concern at first but then he said that it either stretched or shrank and was no longer an issue. I hadn't thought about it until just recently.
My cycles have been really wierd. They are getting closer and closer together and they're much heavier. I was always regular and light before this last pregnancy. My hormones are also out of balance.
Have you heard if juice fasting has the same effect on these tumors? I have juice fasted many times and was actually planning another as soon as my daughter weaned.
