Best friend question

I just lost my baby 2 months ago. I still cry hard, and a lot. I have been trying to feel normal again but I just don't and nobody knows this better than my best friend does. So she calls me today and tells me that she and her boyfriend are going to try to get pregnant. I want to be happy so bad because I love her so much but I'm not. On one hand I'm excited because I know she has been trying to talk to her boyfriend about this for a year now, on the other hand I feel like she may have been insensitive in sharing this with me right now. I don't know what to feel. I love her so much, what do I need to do?***I also know that this is a problem I am having, not her. She should not be expected to put her life on hold because I am grieving. I'm looking for advice on what to do to get myself out of this mind frame.
