Pregnant but negative test

How many of you have been pregnancy but had negative tests? With my daughter I tested as dark as it gets the day of my expected period. Last 3 months I have got my period by the 30th, this cycle I never had a positive opt but the 22nd I had one spot of blood which i assumed was ovulation bleeding. 30th came and went and I started having heavy wet white discharge and then the 7th I had one more spot of blood. I have been taking pregnancy tests every other day and today it's still negative. However I feel that I'm pregnant. I'm nauseous, always hungry, tired, sore breast, the leg cramping at night( only happened while pregnant with my daughter), heartburn and my cervix is high, very closed and somewhat soft which is not normal for me, since my daughter it is always very low and very open. I know it's possible for false positives as a friend of mine was 3 months before she got a positive and my cousin literally tested almost every month always negative and felt something move in her belly so she went in and ultrasound showed a 6 month baby.
