Helpp!

So my husband and I have just started trying to conceive recently and after my first cycle I started getting signs of pregnancy. My taste buds were weird, Everytime I would try to drink a pop it tasted flat, random foods just smelling them made me sick, ect. I stayed tired. My period was do 4 days ago and I missed it but started spotted this morning. I've took like 7 urine tests all negative. What's the chances of me being pregnant.? I really want a baby.
