Hay anak, puwede na yan maging maraming bagay kaya please go to your OB or clinic as soon as you can, mas okay kung ngayong araw pa, lalo na kung may sakit or parang abnormal talaga ang feeling mo, ok? One of my mum friends na may similar sensation din, kailangan lang niya ng check-up to rule things out. Huwag maghintay, better safe than sorry lagi with anything involving the belly!
