first time TTC

I am now six days late at present. The same thing happened to me last month and then I came on  it's like being teased!! I'm never usually late bar last month. I do no that this month I have not been fixated on TTC, and have tried putting it to the back of my head to see if it would help me so that when I do get my AF I'm not so upset. But now I'm late it's all I keep thinking about!!  does anyone or anyone who's been pregnant before know if a lot of discharge instead of AF is normal? I also keep having twinges around my hips and shooting pains come and go but only lightly and not for long. My boobs don't feel sore at all though? & tested yesterday and still saying negative.
