S.M.
I thought I was having a reaction to BC when I STARTED a new med last year. But the doctor said that it was unlikely because I was also spotting. Too high amounts of homrmones cause one and too low amounts cause the other. Anyway, she gave me a perscription med for heartburn to see if it helped - thought it might be stress related heartburn - something like Prilosec/ Anyway, that knocked it out in a few days. My point is, as I was surprised to discover, it is not necessarily hormones. I too have never had stomach problems, except morning sickness.. COnsider it is not BC and visit the doctor to check other possibilities. Also, get a blood test for pregnancy. Feel better.
