Hi There, I Was Prescribed Augmentin As.an Antibiotic As I

Hi there,
I was prescribed augmentin as.an antibiotic as I had a sore throat.I am taking an oral contraceptive pill called microlite. On the first day I took the antibiotic I had sex not using another protective barrier suxh as a condom as I didnt realise and thought as I was taking my pill I would be fine. I have read online since then and am very worried as I see antibiotics can have enzyme inducing chemicals that reduce the effectiveness of the pill. I havent had sex since that time and am very concerned now. I also have a week or soo till my next period is due. I wanted to know how at risk I am as after looking up articles it suggests only antibiotics prescribed for.illnesses like tb and hiv include this enzyme inducing chemicals. Any advice would be soo much appreciated.
Kind regards,
Ms Kennedy
