I'm on my second cycle of TTC after being on the pill for about 10 years. AF is in theory due tomorrow, and for the last 2 days I have had light spotting. Today it is quite a bit heavier... but still dark brown/maroon coloured and a bit stringy (sorry if tmi!) 
Am I kidding myself, or is AF on the way? I was mega tired yesterday and the day before - a little better today after resting, and have the biggest, sorest boobs I have ever had in my life! I've also had a crampy tummy, been emotional, back achey and irritable.
Any ideas gratefully received... Thinking back to before I was on the pill I used to have painful periods, but never PMS. Any of you that have come off the pill - did your periods change?
