Spotting at 29 weeks (7months)

Hello po, pag gising ko ng umaga may brownish sa panty kona spotting, as in spot po or tulo lng mga tatlong patak. Is it normal at this stage of pregnancy? Kasi nagspotting ako nung 1st trimester which is not normal kaya pi- nagtake ako pampakapit. But now kasi I'm at 3rd trimester. Hindi naman nasakit puson ko wala naman pain nararamdaman .Have you experienced this also at this stage?
