Ay, mama, that sounds frustrating talaga, that feeling na mainit ka but thermometer says you're fine is confusing! Honestly, a lot of us moms experience na parang may lagnat vibes pero walang actual fever, lalo na pag stressed or nahihilo, so you're not alone dito. Since may headache ka pa plus the body heat feeling, I'd really suggest checking in with your doctor kahit parang minor lang, just para ma-rule out kung may something going on, better safe than sorry, especially pag first-time mom ka pa lang and learning your own body. In the meantime, rest as much as you can, stay hydrated, at i-monitor mo if may other symptoms na sumama-sama na.
