Missed period for two months

So I have missed my period for almost two months and everytime I think Im about to start I just spot light pink a week before that my period would have been due. The first time I thought it was due to stress but now it’s just freaking me out. My period has never been this late before I have taken one home test and it was negative. I’ve had no pregnancy symptoms at all. My next period is due in 5 days and I spotted light pink yesterday. Has this ever happened to anyone,?
