Uy mama, 38 weeks na talaga! A few of us moms tried walking more (like mall walks kasi mas okay ang pavement), pelvic exercises, and staying hydrated, pero honestly the best thing is still to check with your OB what's safe for your specific situation, sometimes cervix takes its time pa lang and that's totally normal din! Puwede mo rin i-ask your doctor kung may specific position or activity na mas makakatulong, kasi every pregnancy is different talaga and they know your history best.
