Ttc is driving me crazy!

AF was due today, started spotting this morning and it was light brownish. Thought for sure AF was going to be in full swing before too long. I've been up and around cleaning all day and I've had absolutely nothing, not even more spotting. I've taken several tests and they're all definitely BFN's. Ttc is seriously taking over my life, all I want is another baby! Please tell me I'm not the only one. Ugh... Rant over, thanks for listening.
