Need motivation!!

I have the luxury of not having to work while I'm pregnant and I just can't seem to get myself to the gym. I have no motivation and when I actually do end up going there ends up being so many people there I don't want to do anything. I used to go to the gym with my boyfriend everyday before I was pregnant and now I just can't seem to get up and go even though I have plenty of time!! Any advice, tips, people going through the same thing?
