Ah sayang, pain down there during pregnancy is actually quite common, especially as you get heavier dan baby pressing down more! A few of my mum friends complained about the same thing around 30-32 weeks, it can be from the pressure, hormones loosening ligaments, or sometimes thrush which is super common in pregnancy juga. Better to check with your doc or midwife cepat-cepat je to make sure everything is okay and get proper advice, sebab ada banyak kemungkinan dan they can examine properly. Take care of yourself!
