Best friend problems

So long story short.... I have a best friend who lives a couple hours away. We usually talk a couple times a month. Well she's been TTC for over a year. Back in November I found out I am pregnant unexpectedly, I wasn't trying. I'm now almost 14 weeks. When I told my friend, I knew she would probably take it hard, but she's been my best friend for 15 years, so I wanted to tell her right away. She reacted okay at first and was supportive. Since then I've texted her 3 or 4 times and gotten no response. She even sent out a group text to our small group of mutual friends and left me out of it. Two people in that group realized it and messaged me asking what was going on. I don't know what to do. Since then I've left her alone completely to see if she just needed some time, but here we are basically 3 months later and my best friend is completely ignoring me. Our birthdays are coming up very soon and we usually have a mutual celebration of some sort... but I guess not this year. Any advice on what to do from here?

UPDATE: I disagree, this isn't all about her. It's about our friendship. It's about the last 15 years we've been there for each other through everything... deaths, divorce, love, all of it. Just days after my world fell apart and my husband left me, I stood at the front of a church supporting her, holding back my own tears, watching my life crumble as she married the man of her dreams, and never once did I resent her for that. I was devastated, but made it through to support her. I'm not saying she should just suck it up and be happy for me, that would be selfish and heartless and immature. I understand that she needs time to be happy about this, but in the meantime, a simple text back would be nice. But to cut me out of her life completely, which is what is happening because even her husband blocked me on Facebook, I don't understand. I went through years of watching her life fall into place after mine fell apart, and I never let it affect our friendship. But now when the roles are reversed, she cannot even acknowledge that I exist.
