Ay, ganyan din si baby ko around that time, parang may partido inside talaga! Normal lang yan mostly, lalo na at malapit na birth at mas maliit na space sa loob, kaya mas mafeel mo ang movements, pero since you're saying excessive, better to mention it sa OB mo next checkup para sigurado lang, they can do a quick check and put your mind at ease, which is always good peace of mind before delivery.
