Once a heartbeat is detected, the chance of miscarriage drops dramatically. Most of first trimester miscarriages happens between 5-8 weeks (most not all) I wouldn't be overly concerned if I were you
When I was 11 weeks and I had what u call a Threatening Miscarriage I was bleeding real bad and had a lot of blood clogs now I'm 34 weeks pregnant and he is doing very good.
Unfortunately miscarriage can occur at anytime, but if everything is going well for you i wouldn't worry. At this point the chances are slim :)
Sorry what I meant was I really don't know what are your chances
I really know what are your chances but I think you shouldn't worry because your not bleeding
I would recommend you to rest and don't stress.
Find a dr you could trust....
