10 days late now but bfn

Gghft
Hi I'm now 10 days late, really really confused as I seem to have symptoms 
•about 3 weeks ago had light pink discharge but only when I wiped - lasted for maybe 3/4 hrs
•more tired than normal
•boobs v tender
•urinating more frequently (normally 3/4 times a day but now 7 at least)
Tested yesterday and it's negative but in 3 years of ttc this is the latest I've been
Any advice :)
