If you had unprotected sex on the 15th of August and this fell in your fertile period, then you could be pregnant, especially since you missed the period. Chances are less likely but cannot be ignored completely.
The home pregnancy tests are quite reliable but if not done correctly can give a false positive or a false negative result. Tests done at labs or an ultrasound are thus more accurate.
Bulimia, stress, alcohol, poor diet, anemia, and smoking, etc., can all change the pattern of the cycle and delay the period. Hypothyroidism, contraceptive pills, and polycystic disease of the ovary can cause delayed or missed periods.
It is difficult to determine the cause over the internet. Please consult your gynecologist. Hope this helps. Take care!
