How does one differentiate between stomach pain from taking Plan B and stomach pain from an ectopic pregnancy?
Stomach pain is a typical side effect of taking Plan B but there is also a small risk for an ectopic pregnancy, which has a symptom of stomach pain. How does one tell the difference? What other symptoms would indicate an ectopic pregnancy rather than just typical side effects of Plan B? Thanks. A: Plan B prevents pregnancy just days after the woman has sex. An ectopic pregnancy takes just as long to implant as a normal pregnancy, 7-10 days. An ectopic pregnancy has pain located mostly on one side and may move to the center of the abdomen. It’s extremely tender and the woman may have nausea and dizzyness. Hope that helps.
