Having a hard time being young and pregnant

Hope
Being pregnant has made me feel more lonely than normal. I have an isolated lifestyle unfortunately. I don't have coworkers at my job because I'm a nanny for one family, so my only adult time is when my SO gets home from work and then I feel clingy. We moved to this area for work and I don't have many friends over this way, and the ones I do are all my age (22) and don't understand pregnancy. They just want to go to bars all the time. I didn't like that before being pregnant, and my best friend moved for work.
It's hard to make friends when I don't meet new people pretty much ever. My SO gets his guys nights and hangs out with his coworkers, but I don't have my own group of friends and it's really upsetting! 
Does anyone else have to deal with this? Is it just the hormones making me feel worse? 
It didn't really bother me before being pregnant.
