I'm 10 weeks pregnant. I did a flush and modified 5 day program (not full fast) earlier on in my pregnancy after several attacks and had relief for a full month after having attacks once or twice a week. Now they are back again along with annoying constipation that won't quit, I am living on intestinal #1 right now, and I have done another 5 days. What is an average time period to be free of attacks? How many flushes does it take on average to get rid of them? This is pretty nervewracking now especially!!
