Congrats on your pregnancy, mama! A mild fever and sore throat are pretty common, especially during pregnancy when our immune system shifts, pero mas better to check with your OB agad kaya lang, they can properly assess kung ano ang causing it at what's safe for baby at you. One of my mum friends had the same thing early pregnancy and it turned out to be just a viral infection na nawala after a few days, but her doctor still wanted to monitor her, so don't skip that check-up ha! Take care of yourself, drink lots of fluids, and hopefully it passes soon.
