Question. Friends, now not friends?

When you ladies became pregnant did any of you find your friends treating your different or pushing you away. It may be only me and maybe because I'm a young mother, but my best friend I've know sense the 6th grade as really switched up on me. Here we are now about to be in our first year of college and she's been acting really different. In fact I don't even know if I can consider her a best friend anymore or even a friend at all for that matter. I'm just wondering if any of you had to deal with something like this and how did you manage it?
