Blood?

Hi po mga mamsh! I'm 29 weeks preggy po now and medyo worried lang, kanina lang nangyare to ask ko lang normal po ba to, pag ihi ko po kasi kanina, when I was drying with tissue po napansin ko parang may very very light na parang blood marks dun sa tissue, normal yellow naman po color ng pee and wala din blood sa panty ko pero parang mas heavy yung white discharge ko the past 2 days tapos ngayon may ganito, pa help po... Dapat ba ako mag worry? I'm okay naman po hindi nahihilo or anything, I'm drinking a lot of water din po and normal naman counting ko ng kicks ni baby... any advice?
