12dpo still with no BFP.. ?

My husband and I started TTC at the beginning of October. My periods are 7 days long and I have a very regular 26 day cycle. I am supposed to Start my next period Nov 5. I have now taken 3 test all with BFN. I have many symptoms. I know early pregnancy symptoms can also be PMS symptoms but I never have cramps or bloating or anything like that before AF. I am totally hoping for a BFP soon!   Should I test daily or every other day? Only once a day? Or morning and evening? I know to use FMU.
