In brief: Normal variation

What you described falls within the usual variation in cycles.
If you had unprotected sex, it would be prudent to repeat the pregnancy test in 4-5 days unless you get a period before then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex.
