Has anyone had really bad and prolonged stomach pains after taking Eliquis?

Gastrointestinal
Very common (10% or more): Nausea (14.1%)

Common (1% to 10%): Constipation, vomiting, diarrhea, abdominal pain upper, abdominal pain, dyspepsia, gastritis, gastroenteritis, toothache, gingival bleeding, rectal hemorrhage, dyspepsia, gastrointestinal hemorrhage (including hematemesis and melena),

Uncommon (0.1% to 1%): Major gastrointestinal bleed, hematochezia, hemorrhoidal hemorrhage, hematemesis, melena, anal hemorrhage, occult blood positive, occult blood, intra-abdominal hemorrhage, mouth hemorrhage

I kept on searching and came across that SEVERE stomach pain must be reported to your Dr. immediately.
