help?!

Jessamyn

I need some advice...so basically Af was supposed to start exactly a week ago and it still hasn't come. I have had every pregnancy symptom there is, headaches, nausea, breast pain, fatigue...you name it I have it but I keep taking pregnancy tests and they are negative. I am TTC so being pregnant would be great but I feel lost without a positive pregnancy test. I don't know what else to do. help please?
