too early to test?

Kait
11 DPO. Period due 14DPO...having a lot of symptoms, but it could also be environmental factors...but I've never had SO many symptoms before. I have a first response early test (only 1; tested 2-3 days ago and got a BFN), and a dollar store test. I don't want to waste either of them if it's likely I wouldn't get a line if I AM pregnant. I told myself I would test tomorrow but I'm super restless today. Should I test today? It wouldn't be anywhere near FMU; it's already after lunchtime.
