8days late. Need advice

I'm 8 days late in my period, af was due 10-26-16. Been feeling nauseous for about a week now, watery cm, Moody, and tired. I tested the day Af was due and it was negative and took a test 10-30-16 and it was negative. Been told by many people that they was like 2 weeks late before testing positive. I do have a 4yr old son, but that pregnancy was weird, had no symptoms just missed period. I need advice.!!!
