I need advice please 
I was on the depo jab for a short while and my periods came back in September. I was due a period 33 days ago and haven't had my November or December period.
Because of this I did a test 24 days ago and 21 days ago but they were negative.
I have just done another one tonight because over the last few days my boobs have been quite painful and binned it after less than a minute. I revisited it after a couple of hours and there was a faint-ish pink line. I have researched evaporation lines are apparently these are supposed to be colourless however my pregnancy line is pink?
Could I be pregnant? I am so hopeful.
