Just wondering. ....

My last period was sept 4 it lasted 4 days then 2 weeks later I spotted then had creamy milky discharge and then my period was post to start Oct 4 and hasn't came yet.. I am feeling nausea, lower back pain, tired, funny taste in my mouth all day. Then today runny nose. Took test Thursday it said no health dept told me to test by 16 I'd be 6 weeks if I was.. what you think????
