Awww congrats if it's confirmed! Tapi sakit kepala tu memang common dalam early pregnancy, a few of us had it masa first trimester, some sakit nasib baik hilang after few weeks, ada yang kena jugak throughout. Since you're still breastfeeding your first, definitely check with your doc asap to confirm the pregnancy dan discuss about continuing to pump safely, sebab hormones boleh jadi unpredictable when you're pregnant and nursing. Rest well, minum plenty of water, and don't stress too much yet, the nausea and headaches biasanya normalize once your body adjusts. Congratulations again!
