Tahniah, semoga berita baik untuk you! Memandangkan you ada history keguguran, the best thing to do is to please see your doctor as soon as possible to confirm with a proper blood test or ultrasound, jangan tunggu lama ya, for your own peace of mind and safety. Memang betul UPT line boleh naik lebih terang dari masa ke masa, tapi only your doctor can give you the clearest picture and proper care dari awal. Sending you lots of prayers and warm wishes!
