8 days late!

I am currently 8 days late with none of my normal AF symptoms! We have been TTC since November after getting off BC. The first month after getting off BC I had a 42 day cycle, every month up until now I have had a 28-30 day cycle. I took a test last Tuesday and it was negative. So I thought maybe it's too early and I waited a week and tested yesterday at 1 week late with FMU and I still received a negative. My CM is clear/stretchy and there is a lot of it. I don't want to lose hope but it's beginning to get frustrating! Has anyone else experienced anything like this and got their BFP? This will be my first!
