Still no AF but lots of doubt!

I need opinions and some motivation! I was suppose to start my period on the 6th and it was suppose to go until the 10th. Well it never came and so, of course I took a pregnancy test and it was negative. I am coming up fast on the 2nd week of nothing and plan to take another test. I have doubts and dreams of this upcoming test but I feel so different. I am having a lot of cervical fluid (almost every single day it's like school glue) and having heart burn that I haven't had in a long time. So scared to get my hopes up. Should we be trying to conceive like it says we should even though I haven't bled? What do I do? Help please!!!
