For the past few months (about 3-4 months) I've been having my period on and off, meaning that one day it would go and the next it would stop and then some days where it's heavy flow. After my period I would always have uti(urinal track infection) and sometimes I've had cold sweats. I've been taking cranberry juice and Greek yogurt but it only works for a small amount of time. I was on three different prescipted medication, sorry I forgot the names of them, and all made me vomit, sleep too much which caused me to have really bad headache.
