Typing through the tears

Well, we just got back from the U/S and there is still nothing in the sac. The tech was able to tell me that it got bigger, now dating 6w1d. But that's it. Nothing else to see. I'm beyond disappointed. I'm trying so hard to remain positive, but it's so hard. My heart is just breaking. I don't know what to think. I'm waiting for Renee to call. I'm guessing I'll have to get more blood work and another u/s next week sometime. I'm sorry, but I don't even know what else to write right now. I can't stop crying. God, this sucks.
