Aih, chest pain dari batuk tu memang sakit kan… memang rasa macam otot tegang je sebab coughing fits tu, tapi kalau dah 15 minggu and sakit dada still ada even after batuk berhenti, better check with your doctor la dear, terutama masa pregnant like you, lebih baik jaga-jaga. One of my mum friends had something similar last year and the doctor just confirmed it was muscle soreness, but they ruled out other things dulu which made her feel more at ease, so it's worth the visit!
