Hi ladies I'm in a pickle and need a little help... 

My period was 9 days late then on the 10th day I noticed a little pinkyness when I wiped  sorry if tmi then the 11the day it was a little browner and the same the next day and now today only the pinky colour again when I while but barley anything... There's not been enough to even fill a panty liner over the few days.... I tested negative 4 days after I missed my AF but it was negative then again at 8 days negative again.... I'm normally really heavy with a lot of clots this time nothing like this.... What could this be??  I'm so confused at whether I'm pregnant or I'm flapping about nothing... Should I take another test in a few days??  HELP ladies xx
