Negative FRER (first response) am i out?

Did anyone else get a BFN at 11dpo and go on to have a bfp? I've only got 3 days till my period, started to get some "symptoms" breasts are tender and nipples are itchy (was one of my biggest symptoms when i was pregnant with my son). Ive been feeling nauseous but all tests are negative so far. Would like to hear some experiences, been ttc baby#2 for 6 months some reassurance would be appreciated
