Ay, squatting at walking are great for preparing your body, pero wag mo i-force too much pa since mababa lang talaga ang cervix and you're still closed, your body will open up when it's ready, honestly! A few of us tried similar routines near term at parang the cervix followed its own timeline pa rin, so don't stress too much na parang kailangan mo agad mag-progress. Siguro better to check with your OB kung kelan mo na talaga ma-expect the changes, kasi every body is different and they can tell you kung normal pa ang situation mo. Keep moving pero listen to your body din, and if may doubts ka, mas safe to ask your doc directly. You're so close na!
