Ay, nangyari na rin yan sa amin dati! Brown discharge bago ang actual period is pretty normal kaya wag mag-alala muna, pero since it's stopping and starting like that, mas better kung i-check mo na lang ng doctor para sure, baka hormonal changes lang or maybe implantation if there's a chance, pero alam mo yan ng OB mo talaga. A few of us from our moms' group noticed the same thing months apart, and mostly it was just irregular spotting before the heavy flow came, pero everyone's different so better safe than sorry ha!
