Hey mum, I understand how worrying it is when you're not feeling well in early pregnancy. But this one better not wait lah, please go see your GP or a polyclinic before next week's gynae appointment. They can check you properly and advise what's safe to take during your first trimester, because not all medicines are okay at this stage. Sore throat and runny nose could be just a normal cold, but best to get it confirmed and managed properly rather than self-medicate and risk something you're not sure about. Take care of yourself.
Would not suggest self medicating as most medication not suitable for pregnancy, best to seek doctor. Take warm honey lemon and drink lots of water meanwhile.
