Uy mama, tummy pain kahit kailan ng pregnancy ay kailangan i-check ng doctor talaga, lalo na para sa peace of mind mo, please don't wait, contact your OB agad or go to the hospital if it's sharp or heavy. Kasi alam mo, karamihan ng amin dito may light cramping or stretching pain sa first trimester dahil lumalaki ang uterus, pero dapat sure ka talaga kung normal lang siya o may need ng medical attention. Better safe than sorry, di ba? Sending you love, sana everything's okay with you and baby!
