Sabar ye, I understand your concern especially after what you've been through. A few of my mum friends pakai implant and most say it's reliable, tapi memang ada yang experience spotting or mood changes for the first few months, it settled after. Lepas bukak, most got pregnant normally, tapi since you punya history of miscarriages, I'd really suggest discuss dengan your doctor or gynae properly before decide, sebab they can check what caused your previous losses and advise yang safest for you. Wishing you all the best, mama!
