Am I pregnant?!

ok everybody, I am most definitely freaking myself out. My period is 6 days late, I have been taking a test everyday and they are negative. We have been trying to conceive our second child for 5 months now. Symptoms: Cramps Something pulling in uterus Tender heavy breasts More veins in breasts Extreme fatigue Bloated ness Hunger Vivid dreams ... I don't know if I should wait another week and test again... I want to be pregnant so bad but I have no other reason for my boons to hurt. Someone help?!?!
