For the ladies:Have any of you noticed that your menstrual cycles have gotten longer and HEAVIER after starting antidepressent, etc. for your IBS. I started taking Amitryptaline in March and my periods in May and this month have been very heavy. I never had this problem before (would hardly get it at all) and it seems since I started this medication they have gotten much heavier (no pain, just heavy bleeding) maybe its just a oincidence....What do you think?
