Seems like so much

I go in Monday the 16th for another ultrasound. I go in Tuesday the 17th for a regular check up appointment. I go in Wednesday the 18th for 3 hour blood test. I can go in at 9am for blood work, my ultrasound it at 12:15. I want to just do my blood work Monday 16th but I'm not sure if the timing would line up and I can't mess up the last hour of my blood work or miss the ultrasound. Plus having so much blood taken might not be good before ultrasound. It seems like so much only because I'm so exhausted lately. It's also the wait that's killing me. This is still almost a month away.
