Ayyy mama, this is SO normal lah, a few of us were talking about this last month, and honestly at 37 weeks your hormones are all over the place, plus you're probably exhausted and anxious about baby coming soon, so every kick feels like a reminder of all the big feelings inside you already. It's not the baby movements themselves, it's that your emotions are running high and sometimes they come out as frustration or sadness when you notice them. I'd say just be gentle with yourself, try to rest when you can, talk to your hubby or a friend about how you're feeling, and definitely mention this to your doctor at your next checkup so they can make sure everything's okay emotionally and physically, because late pregnancy can be overwhelming lah.
