Hey mama, that's actually pretty common at 8 months, babies explore their bodies and push against things, pero if it's causing you pain, it's worth mentioning sa OB mo next check-up para ma-rule out kung walang complications. A few of us mums noticed our babies were just naturally curious and pushing hard, pero yung pain part you're feeling, better safe than sorry talaga, kaya go ahead and ask your doctor about it para ma-ease your mind.
