It's a sad day...

Kris • I'm 36 years old and this is my third pregnancy. I'm so excited, and staying positive that this time it is different.
I had a follow up u/s today after going to emergency last Week Saturday cuz I had a gush of bright red blood. The u/s was good and baby was measuring 6.2 weeks. The HR was boarderline, but I was hopefully all was okay. At today's u/s the HR was slightly lower and baby only measured 6.3 weeks so hardly any grown in the last 9 days. My OB is hopefull and has me coming back on Thursday for another u/s to see the progress. I can't help but to think that it just isn't meant to be. I had m/c last April and was so excited and really thought this time would be better. Anyone have similar story with a positive outcome?
