Feeling alone..

So I used to have a Bestie . we used to work together which meant we were always together.. Went to lunch together.. Went out together.. Everything. I recently stopped working because I'm pregnant n now we don't even talk anymore. We used to at least text but now we haven't spoken in like 3 months..I ask her about it n she said its because we're both busy..she has her job n I have 2 kids n my pregnancy but me having kids was never a problem before..I just miss her so much..I miss having someone to talk too .. I feel so alone I mean don't get me wrong I have a very supporting husband but I need a girl friend to talk too especially since this pregnancy has me very emotional :( what can I do?
