I and my girlfriend had unsafe sex on 31 dec , next she had taken unwanted 72 pill to prevent any unwanted pregnancy, in the evening she felt fever and had taken paracetamol and antibiotic medicine , on 3rd January she bled little bit in the morning, after that no bleeding or withdrawal bleeding has occurred yet , will antibiotic medicine can hamper the effect of unwanted 72? Will there be any chance of getting
pregnant anymore?
