Wondering..

I wonder if what happened in the past (missed miscarriage last April) is giving me all this worry. I'm trying so hard to stay positive. But my first appointment is forever away and I'm so nervous because I didn't have any symptoms for my mmc last year.. No cramping or blood.. And I guess all I can do is wait and pray but I can't help but think of the what ifs like progesterone levels and all of this... My mind is going crazy and I still have a month until my first appointment. I don't even know if I'll get an u/s at my first appointment.
