period question?

i came off of the pill about 3 months ago and my first period came quickly after coming off and it was a week long and i felt crappy (cramps) but my two most recent periods have been 3 days (4 at most) long and i havent really felt too bad. its like i know its there and theres a good amount of blood but i dont feel nearly as bad as i used to. is that bad? is this normal?

Also: i have a burning sensation a couple days before my period, is that normal?
