Haha I feel you lah, those last few weeks memang the longest! Honestly a few of us tried walking a lot, doing squats, eating dates, one of my mum friends swears the dates helped her, but honestly it could be placebo juga haha. The thing is, baby will come when baby is ready, so don't stress yourself out too much trying to force it because that actually makes things slower. Since you're already 38 weeks, definitely have a chat with your gynae at your next checkup about when they want to monitor more closely or if there's anything you should or shouldn't be doing, they'll give you the best advice based on how your pregnancy is progressing! Hang in there, you're so close now!
