Light pink discharge after period?

Hi,

So you get the full picture... my period before last started on the 18th of November which was fine, my periods usually come every 32 - 34 days but my last period didn't come until the 27th of December  (41 days) it was more watery than usual but lasted 3 days so I just assumed it was another period.. although today (4 days after my period finished) I have got slight pink dishcharge.

I have booked to see the doc but she can't see me for 2 weeks and I'm really worried as to what is going on?! I don' think im pregnant but what can it be?

Hope someone can help me??
