Ay nako, I understand the worry! Fever during early pregnancy is definitely something na dapat ma-check with your OB talaga, kasi important yun sa development ng baby especially sa first trimester, better to get proper guidance para sa peace of mind mo. A few of my mum friends had fevers early on din, pero lahat sila nag-consult agad and thankfully okay ang babies nila, pero super important talaga na ikaw may personalized advice from your doctor since every pregnancy is different. Kakatuwa naman na first-time mom ka pa lang, congrats sa babe!
