HI, I Just Noticed 5 Sudafed Tablets (I Have Taken

HI, I just noticed 5 Sudafed tablets (I have taken 2 a day for about a week) and one other tablet (possibly metformin?) in my stool. Should I be concerned? I am a 57 year old female w/type 2 diabetes for past 11 years. Yes, I am overweight, always have been. I am never sick until this year I've had 3 colds, one that turned into bronchitis (first time ever).
