I need opinions!!

So my period was supposed to start 6 days ago my cycles are 30 days long and a week before my period was supposed to start i have very light pink spotting (like just a drop or two of blood) but it happend a few days prior to that. Im 6 days late and I cramped really bad a day ago and now its gone, still no period.. i have no other symptoms besides the missed period and the pink spotting. I have a daughter right now so i know how it feels to be pregnant, and i dont feel anything?? 😐 ive taken a few pregnancy tests and they are all negative i took one 2 days after my period was supposed to come and it was negative?? Any thoughts??
