Ah sayang, insomnia memang common bila pregnant, especially around 15 weeks! A few of my mum friends said they had the same issue, badan dah mulai uncomfortable, hormones everywhere, plus anxiety about baby lah. Try sleeping on your left side with a pillow between your knees, avoid heavy meals and caffeine after 2pm, and maybe do some light stretching before bed, memang membantu some of us. Tapi kalau tidur terus-terusan problem or you're feeling exhausted banget, best check with your doctor kay because sometimes badan kita ada needs yang need attention during pregnancy.
