Hai sayang, I understand how worrying this must be for you. The thing is, spotting on and off dalam early pregnancy is actually quite common, especially kalau period cycle you biasanya tak regular pun, and the cramping you're experiencing boleh jadi normal stretching je. Since your LMP is 24 Aug, you might still be quite early; many mums told me that kantung sometimes takes a bit longer to show up clearly, and the doctor's suggestion to repeat the scan dalam seminggu or dua minggu is actually the right move, most of the time, baby will be there perfectly fine when they scan again. I've heard from quite a few who went through exactly this, spotted through first few weeks, and delivered healthy babies at 9 months. The key is just to go back for that follow-up scan as advised and let the doctor monitor your HCG levels if needed. Wishing you all the best, and do keep communicating with your doctor about any changes, they know your situation best, eh.
