Af Was Due 3/14 now 13DPO

Kitty • TTC Baby 1
Ive been having back pain for 2 days now followed by 4 days of heavy sensitive breasts. Early today I got very light pink almost faint spotting. I'm extremely Tierd and don't have much of an apatite. Been TTC. Is it to early to test? Am I just getting my hopes up?
