Sayang, rasa berdebar dan kencing kerap dalam first trimester memang common sebab hormones berubah drastis, tapi kalau dah a week berdebar terus macam tu, better check dengan doctor eh, bukan nak takutkan, but they boleh check blood pressure and thyroid just to be safe, especially since kau first time pregnant jadi good to rule things out. A few of my mum friends experienced similar tapi it settled down after a few days, but yours lasting longer so worth getting professional advice lepas tu kau boleh rest easier!
