Jay Jay - welcome to BellyBelly, I am sorry you have something frightening to introduce yourself with.

There is an article on the main site that talks about different reasons for bleeding which may or may not help, you can find it here. I agree with taking it easy, especially if it's thought your placenta is low down. I'd probably avoid sex until it's confirmed too. Let us know how you go, its great news that bubby is there and active and that the bleeding has stopped - hang in there and we'd love to know how you go with your scan.

I'll move your post to the pregnancy section so you can get more advice.
