I am glad you found us and welcome to Belly Belly...
This is a very stressful time for you, and I am sorry you are having to go thru this.
In another week you will be able to have a diagnostic u/s which will show just what is happening in there. However, if your hcg levels are within range and approx doubling each 48 hours that is a really really good sign.
Many women suffer bleeding in pregnancy and go on to have healthy babies. I myself bled quite significantly (including clots) with my DS who is now a gorgeous 7 year old!

By around 7 weeks you "should" be able to see a heartbeat on u/s. Often before this but by 7 weeks it is usually seen.

Wishing you all the very best - there is a plethora of wise women in here who will help you and support you...
