Missed my second period after intercourse

 Me and my husband had protected intercourse twice (he used two condoms each time) and condoms were not leaking since we checked it after each intercourse. Even with the condoms he came outside. I have a 30 day cycle with 5 days mensturation and we had sex around the 24th day of my cycle. I had a normal period immediately succeeding the intercourse but my second period is late by almost 8 days. Other blogs do not clearly help in terms of whether its normal or not. Somebody pls help with some proper information. Is it possible to be pregnant.
