Not enjoying pregnancy yet :(

This is my second pregnancy, first baby. Last year I had a mmc at 6w5d. . Didn't find out until 10w. This time, I seen the heartbeat at 7w2d and everything seems to be progressing well. I have my next appt Aug 24 at 11w2d and I am worried about everything else but enjoying my pregnancy. If I am not thinking about MC, I am thinking about L&D. I am trying to prepare myself but I think I am driving myself nuts!! I am sooo tired and don't hAve energy for anything. My fiance and I are getting married in Nov and I am worried about that too! When can I just enjoy my pregnancy??? When can I have a moment to just rub my belly and feel like everything will be okay? I am trying to be positive and my SO is such of a great motivator. He is amazing, but I'm just scared of everything right now. :(
