Blood loss

Lilly
Hey,
Is there anyone else who is loosing blood every day? It started when I was four weeks pregnant. I am now 9 weeks and still have blood loss every day. Sometimes it's red, sometimes it's pink. It's not that much but I am very worried because i sometimes have cramps. I had an US at w6 and w8 and the little baby is doing well. I have to wait until week 10 to have another US, but I  am so worried all the time. It's my first . Does anyone had or has the same problem?
