Sayang, I know it's scary but please don't wait, go see your doctor as soon as possible, okay? At 7 weeks you should be able to see a heartbeat, so it's important to get checked properly rather than worry at home. A few of my mum friends went through bleeding during early pregnancy and alhamdulillah babies turned out fine, tapi each situation is different and yours needs professional eyes. Jangan delay, go to your clinic or hospital this week lah. Sending you strength!
