Sayang, swollen and painful underarms during pregnancy boleh jadi normal sih, hormones and fluid retention memang suka buat macam-macam, and sometimes lymph nodes pun bengkak sikit. But sebab you're having pain in both armpits at the same time, better check with your doctor or gynae just to be safe, tau, especially since pregnancy immune system lain sikit and we want to make sure it's nothing like infection or anything else that needs looking after. One of my mum friends had the same thing and it turned out just hormonal, tapi doctor still took a look, so peace of mind je, worth the appointment, syg.
