Mama, please see your OB as soon as you can, especially with the belly pain, weakness, and fatigue all together, kailangan na i-check properly. Hindi ko kaya sabihin kung normal lang yan or kailangan ng alagaan, kaya OB na talaga. A few of us moms had different experiences sa first trimester, ang isa nag-alala ng ganyan, nag-labs lang at okay pala, pero kailangan mo ng checkup mo mismo. Huwag mag-antay pa; puntahan mo clinic mo or call agad. You and baby deserve proper care, di ba? Rest muna while you arrange that, take care of yourself!
