I could be up 2 3 weeks out but no more than that I no I'm probably just grasping at staws hoping that there could still be a baby there :(
To be totally honest with you...
If you are certain you are 9 weeks, and the sac is measuring 5 to 6 weeks with no fetal heartbeat, plus bleeding and clots, this does sound like a loss. I obviously cannot diagnose, and you should go back for your second scan, but based on this info this is what it does sound like. I'm so sorry. I hope that I am wrong and all is well. Please take care, I know this is a very difficult thing to go through. Is there any chance you could be 3 to 4 weeks off on your dates?
I would go to the ER right now and tell them you lost cloths, its different when your loosing cloths than when your just spotting. They will either confirm that you are indeed still pregnant or if you miscarried....
