Ovulation???

Sarah
Help!!! I'm TTC. Had my period on sept 14-18, I started doing a ovulation test on sept 22 it is now oct 2 and I still haven't gotten a good fertility. I am using the clear blue digital and all I get Is a plain circle  indicating low levels. :(  I'm starting to worry and get a lil scared we won't be able to conceive. This is the first
​Month we have done the ovulation test. tIA
