Hey mama, tahniah dulu pada pregnancy baru ni! Jangan risau, memang boleh jadi hamil cepat selepas keguguran, lepas miscarriage tu, hormon hCG turun cepat, so ovulation boleh happen dalam 2-3 minggu je, sebelum period dtg pun boleh. Macam my friend keguguran in January, terus positive in March, so it happens!
Tapi sebab ada history gugur, memang la kena go to clinic ASAP untuk full check-up, scan, and see what your doctor recommends, ada certain supplements like folic acid or progesterone yang some doctors suggest to support early pregnancy, depending on your situation. At 6 weeks mmang belum nampak banyak in ultrasound, but your doc boleh assess your hormone levels first. Jaga baik-baik ye, and do get proper medical guidance sebab setiap pregnancy and every mum ni lain-lain. Wishing you all the best!
