Sayang, I know it's scary especially when you're pregnant! But with your history of TB and bronchitis, plus this happening again, you really need to check with your doctor ASAP, jangan tunggu 18/5, boleh call clinic and explain the situation, mungkin dia boleh squeeze you in earlier or give guidance over phone dulu. A few of my mum friends yang pregnant pun had persistent cough, and most of them kena see their OB + GP together to make sure whatever they take is pregnancy-safe. The antibiotics your clinic prescribed before, you need to confirm with your doctor if it's okay to take now that you're pregnant, because not all are. For now, try the basics: stay hydrated, elevate your head when sleeping, and avoid triggers kalau ada. But please jangan self-medicate even with the old prescription, pregnant mums need different care, and your doctor needs to know about the chest pain and vomiting too. Sending you strength, mama!
