TTC 6 months

Kristin

My husband and I have been TTC for 6 months. I have been having some symptoms that I can't tell if there PMS symptoms or pregnancy symptoms. I'm 11 DPO according to my glow chart but I got a BFN test this morning. I have been having headaches for the least two day as well as bloating,gas,tender breast (no more then usual when AF comes) and yesterday I had cramping but no spotting. This is my first time TTC so I'm I just paranoid or do you think I might be pregnant just without enough hormones to register on the test?
