My Boyfriend And I Had Unprotected Sex On 16th Of

My boyfriend and I had unprotected sex on 16th of April and I used postinor 2 as an emergency contraceptive. Over a week after ,this happened again and I took the same preventive measure only not completely. I feel feverish right now and I am expecting my period in a few days. I also took paracetamol and ampiclox this evening incase there is an infection but my greatest fear is being pregnant. How can I get help!
