Wa'alaikumassalam sis! Bleeding masa pregnant especially at 12 weeks tu memang bukan normal situation, even kalau sikit, kena check dengan doctor asap, jangan tunggu appointment sebulan depan. Please go to A&E or call your gynae today, okay? Bleeding at this stage kena investigate properly to make sure baby okay. A few of us went through scares macam ni, and honestly, peace of mind is worth getting checked immediately, tak payah tunggu. Doctor will want to do ultrasound and proper assessment, so don't delay, sis. Take care of yourself
