Mama, yan na ang safe recommendation ng doctor mo kaya okay lang! A few of us moms got sick early pregnancy din, and honestly the meds the OB gave were all pregnancy-safe, chlorphenamine at paracetamol ay commonly prescribed talaga sa buntis na may sakit, so don't worry. One of my mum friends had terrible cough at 8 weeks pa lang, nag-follow lang sa doctor's orders (similar sa sa'yo), and healthy ang baby nang ipanganak niya, the important thing talaga is you rest, hydrate, and take exactly what your doc prescribed. Sundin mo lang ang instructions with the vitamin C, gargle, at monitor if may fever, at remember na being sick while pregnant is scary pero managed well with proper meds, baby is protected din.
