13dpiui BFN :( Am I out??

Savannah • I`m 30. Had baby #1 after 3 years of TTC, 1 year of fertility treatments. Going to try for#2!
I go in tomorrow (Monday) for my beta.... I've been testing everyday since Thursday to give me something to do so I won't go insane... All have been BFN. No sign of AF yet, but I'm not feeling very hopeful :( any one have success when getting BFN on 13dpiui?
