I had unprotected sex and took the Plan B generic

Patient: I had unprotected sex and took the Plan B generic version Altera pill about 30 minutes later. it has been about 3 hours since this incident, and my head is pounding, I’m slightly nauseous, and my heart is beating extremely fast. my calves hurt and my head feels like it is on fire! should I go to the E.R. ?
