Aww mama, sakit kan, tapi alhamdulillah dah habis! A few of my mum friends got the dexamethasone injection around that time and they all said the same thing, it's uncomfortable but so worth it sebab it helps baby's lungs develop faster just in case. Most of them delivered on time or close to it, so fingers crossed for you! The soreness should fade in a couple of days, and you're doing amazing for taking care of baby like this. Aminn aminn, baby will be strong and healthy!
