False negative?? Help needed!

Okay so I know this test is definitely a BFN. I tested Saturday morning with FMU and I was 11dpo. Came back negative and my fiancé and I were disappointed and also confused because I've been having a bunch of symptoms... Sore/heavy/tender breasts that seem larger, major bloating, extreme fatigue, headache, backache, moodiness, cold symptoms, nausea, urinary frequency, sensitive smell... Etc etc. I know some of these could be PMS, but I never have most of these with PMS and never this bad. Is it possible this is a false negative and I just tested too early, or am I just getting my hopes up??
