Hai! Okay this one kena tanya doctor atau midwife you betul-betul, sebab kat 38 minggu ni sensitive jugak and depends on what type of infection or discharge you have. Jangan self-medicate ya, better safe than sorry especially nearing labour!
Honestly a few of us mums kena deal dengan keputihan last trimester jugak, tapi semua kena get the all-clear from doctor first before pakai anything insertion. Go see your OB or midwife ASAP okay, they'll check and advise what's safe for baby. Sending you all the best!
