Can Tums Cause Your Stools To Be Dark In Color?

can tums cause your stools to be dark in color? Also, I vomited this morning thinking I had a virus. But, afterwards my stomach has been hurting very badly. I have had stomach ulcers before and threw up only after within an hour of eating. This time I ate at 9PM went to bed at midnight and was up at 4AM throwing up. Not sure if it is a virus or ulcer.
