I Was Prescribed To Take 500 Mg Of Amoxicillin Every

I was prescribed to take 500 mg of amoxicillin every 8 hours after a dental surgery that I have yesterday but I just start take the amoxicillin today I was in very pain I take one at 8:30pm and then I still feel a lot pain and I have a fiver in 101 so i take a 600mg of ibuprofens around 10:45 and then I still fell so much pain so I take other amoxicillin around 11:10 pm I should, be worried about something?
Thank you
