I am 15 and about 7 weeks pregnant. And I have been experiencing some bleeding. At first it was Brown blood and I only saw it when wiping.this is the third day and now the blood is red and there is more blood than the first day.. it's to where I can see a hint of blood in the toilet... and I am getting very worried...

You should be. At 15 your body may not be developed enough to go through a pregnancy. So you could be miscarrying.

How do you know you are 7 weeks? Have you seen a doctor? You need to consult with your doctor immediately. Or go to an ER.

Any bleeding during pregnancy is a cause for concern. What did your OBGYN say when he/she examined you when you told him/her about this bleeding?
