Hai sayang, rasa berat dan ngilu-ngilu di area kemaluan memang common dalam pregnancy, lagi-lagi second trimester, tapi sebaiknya check with your doctor je to be safe, bisa jadi dari weight of baby, ligament stretching, atau hormones, tapi dia kena confirm. A few of my mum friends went through the same thing around 15 weeks, some rasa better after wearing a maternity support belt, tapi everyone's different la. In the meantime, try resting more, elevate your legs, and avoid standing lama-lama if you can. Jangan worry dulu, but do get it checked out with your gynae just to make sure everything's okay, okay?
