I went to my doc today after suffering with bad IBS for a week running up to and including my period. I explained to her that I have full on attacks at this time and think it is due to hormones. She told me that since my contraceptive pill was 'artificial' hormones, they could not be the cause. Only 'natural' hormones that are up and down can be blamed for symptoms??? I was very confused at this. I know that something goes on around my period to cause these week long attacks! She prescribed a drug called 'Spasmonal' which I will try for the cramps, i hope they might help. Has anybody else tried this?
