Insomnia and other symptoms during TWW

Second night straight that I wake up in the middle of the night and just can't go back to sleep... af due on the 26th. It could be anxiety. But I don't feel that anxious during the day. Sometimes I even forget about it (just for short periods of time. Lol). I still haven't tested and want to wait until after. Trying to stay strong. What are some of your symptoms during this tww?
