problems?

ok so my last period ended on the 30th of last month, then suddenly for some reason i start having some brownish red discharge monday morning, but ignore it, then yesterday it started becoming red like a period so i put a liner on to keep my panties from being destroyed, now today i had to go full pad and tampon cause it was like i was back on my period, ive never had this happen to me before and google isnt much of a help. so i ask of the ladies on here, is it normal to have this happen? or is something possibly wrong?
