Alahai, I haven't personally taken labetalol myself tapi satu dari mum friends ku ada kena high BP during pregnancy and she was on it, dia cakap side effects mostly manageable, just felt a bit tired the first week or two but it settled down. Since you just started this week, tu normal lagi your body adjusting, so give it a bit more time and monitor how you feel. Definitely reach out to your doctor if you notice anything yang buat you worried or kalau side effects tak hilang, okay? Minum plenty of water, try to rest when you can, and jangan stress sangat, semua will be fine! Let me know how you get on, I'm sure other moms here also have experiences to share once they see your post
