Blood sugar should be between 4 and 7 generally, so while your morning fasting is at the higher end of acceptable it isn't anything to worry about.
Unfortunately the symptoms that one person has when low can be very similar to what another suffers when high, the only way to check is with a meter and eventually you will find out what your symptoms are for lows and highs. If you do start to feel unwell the best option is to test, and also remember that other things apart from BS levels can effect how you feel so it is always best to test.
