I'm not social as I used to be

Cindy • I'm a stay at home soon to be mom. I'm so excited! We are expecting a beautiful baby girl :-)
Ever since I found out I was pregnant I kinda distance myself from people, and I make a lot of excuses not to hang out. I just like being home comfortable but my mom said it's not healthy to keep to myself all the time. All of my friends do drugs and smoke so I rather just be home waiting for my hubby. We have lots of fun cuddling, watching movies/shows and sleeping on his days off. Am I the only one though?
