No usual period cramps before period

So I always experience cramps before my period. Usually 3 days before I actually start. Tomorrow I'm supposed to have started my period but today I saw pink spotting while I wiped down there. And surprisingly slight to no cramps at all. also had diarrhea for the past week. This may not even mean a damn thing but I've been trying for over a year now and I want to know everything lol.
