Third Trimester

Hello mga sis . This week is my third tri na po. Should I start walking na po every morning in preparation for labor? My history ako ng spotting nung March at sinabhan ni OB last month na bawal exercise at sexercise. Sa October na po ako mangnganak. Pero sabi naman ng health center. Maglakad2x n daw ako. Your thoughts will be a great help po. Salamat.
