7 days 22 hours smoke free :)

So today I'm 7 days 22 hours smoke free. I'm feeling much more confident that I can do this. Cravings are decreasing in frequency and length and I'm learning how to deal with everyday stress without running out for a ciggy... I have more time for myself and my daughter along with more money :)... I have noticed that my gums are slightly bleeding when I brush. Does anyone know how long this lasts?
