Help!

We have been trying for a year. I'm new to glow and praying it helps us achieve to get a positive test. I was supposed to start today, (it is usually what wakes me up) but I'm still not spotting or showing any signs of starting right now. I took an early response test a few minutes ago and it was negative. I have endo. I'm so ready to just give up. All I Wana do is cry. I'm so ready for a postive!
