Hey mama! You're doing a lot na ng good things na, walking, squatting, yoga ball, lahat yan talaga helps with positioning at gravity para sa baby. Re primrose oil at pineapple, honestly the evidence is mixed kaya if it makes you feel like you're doing something, continue lang, pero hindi guaranteed mag-soften ng cervix agad. The hard cervix thing is actually normal pa at 38+ weeks, kaya don't stress too much, your body will soften it on its own timing. Definitely ask your OB next visit kung may specific exercises or positions sila suggest para sa your cervix, or if there's anything they'd monitor differently, because they know your full picture best! Fingers crossed baby comes soon for you, mama!
