11 dpo... test or wait?!

Emily
Hi! 
So since about 5-6 dpo I have had nausea and then at 9dpo I started having af style cramps. I've heard that can be a good sign and I never get them so early. I've had bfn this morning but guessing it's still quite early? 
Should I test every morning? Trying not to run away with myself but never felt like this before! And it's normal to get bfn at this stage and still be pregnant right?! Xx
