Eh, this is quite urgent lah, please call Poison Control (03-4588 1616) or go to the nearest A&E straight away, jangan delay. Blood thinning medication is not something to play around with, even if you're not sure how much you took. Tell the doctor or nurse exactly what you took and when, so they can check you properly. I know it's scary, but better to be sure. Sending you strength!
