Hai! I understand la, contraceptive injection is actually quite effective, tapi memang ada rare cases where orang mengandung jugak even with proper use, nothing is 100% foolproof kan. A few of my mum friends use the injection and they're happy with it sebab convenient, tak perlu ingat minum pills every day, but a couple of them did experience spotting or irregular cycles at first. Best thing is to have a proper chat with your gynae or at the clinic about your concerns and your personal health history, so they can advise you properly and maybe suggest what works best for your situation! Nak share lebih details about your concerns or what you're deciding between?
