You're right, 28 weeks is when kick counts really matter kaya okay lang na wala pang consistent pattern ngayon, at 23 weeks pa lang ang baby mo, so the activity will be super irregular talaga! Totally normal yung variation mo, some days active, some days quiet lang, kaya don't stress yourself over it yet. A few of us tried tracking early din out of excitement haha pero realized it's pointless pa, so just enjoy feeling the movements for now at once you hit 28 weeks that's when you can start doing proper kick counts if your OB asks for it. For now kung nag-worry ka anytime, checking in with your doctor is always the safest move kahit FTM ka pa lang!
