6 weeks.

This week is my six week mark.  Still not feeling much in terms of symptoms so starting to get worried.  I'm not even sure if I'm pregnant anymore.  I hope I am but when you don't have any symptoms you start to loose hope.  I am still tired and my boobs feel "full" but I am also taking progesterone supplements so I am pretty sure that the medication would cause those symptoms too.  It's so confusing.  My first ultrasound is scheduled for Monday, March 3rd and I can't tell if I'm excited about it or more scared about it.  I just can't picture them saying everything is normal.  I keep hearing there is no sac, or there is no heartbeat or the heartbeat is measuring behind.  This is just nerve wrecking.  My pure excitement from last Thursday has now changed to complete worry.  I know that I just need to just keep moving forward at this point and what will be will be.
