Alahan pinggang dan cramp perut memang common masa early pregnancy, hun, a few of my mum friends shared the same experience around your weeks, ada yang describe macam period cramps je lagi. Yang penting, try rest more, drink plenty of water, dan jangan push yourself kalau rasa tired, lepas first trimester biasanya settle down sikit. Tapi since you're experiencing quite a bit of discomfort, best to check in with your doctor or midwife just to make sure everything's okay, especially to rule out anything that needs attention. Hang in there, first few weeks boleh jadi challenging but it gets better!
