Threatened miscarriage

Hello mummies, It was an unpleasant news from the doc. I was 7weeks going 8 and I start from blood strain in my discharge. My discharge is clear in colour and I saw blood in it together. As days pass, the bleeding got darker like fresh blood with some blood clots. It's not a lot. But alot to fill up my pantyliner. I went to the doc and they said it's threatened miscarriage 😔 I am so worried for my baby. Anyone experience it before? *Updates* Doctor confirm a miscarriage as at 04/01/22 I'm at my 9weeks. Sonographer cannot detect baby's heartbeat. I'm crashed inside. 😭
