I'm in the same situation basically. 28 weeks pregnant and totally socially isolated by my own choices but not because I actually want to be lonely... I just don't even know how to make friends.

I had a "ready made" friend in a coworker who was due on 9/16 and I failed completely. Never asked her for her phone number to text/chat, never asked to add her on Facebook. She's gone on maternity leave now, I know she's gone overdue because some of my coworkers who aren't social retards are keeping up with her. I miss her, wish I could be closer with her, and I feel so lame for allowing this to happen.

I thought I was handling realizing my own stupidity OK until a few days ago when another coworker was talking about her plans to go to a fair with one of the other ladies we work with and I realized, they've known each other for like 1/3 of the time I've known Preggo coworker and they've become friends and I'm just over here being a total loner and failure. My toddler has never had a playdate because of my social issues.
