In : In general you should not take Amoxicillin if you allergic to penicillin. However, vomiting is not indicative of an allergic reaction, rather more likely a side effect. Many studies have shown that most people who say they are allergic to penicillin are actually not. More likely they had a side effect, or developed a non-allergic rash. Still though, i will generally not prescribe any of the penicillin class of medicines to someone who states an allergy- it is not worth the (small) risk as there are plenty of other antibiotics out there. To know if it was alright to stop taking the medication though- i would need to know what you were taking it for.

Get tested: Amoxicillin is a close cousin to penicillin, ideally someone allergic to penicillin should not receive either. Best answer is to get a skin test for penicillin by an allergist and determine if you are truly allergic to penicillin.
