feeling broken

So myself and my husband have been trying for a baby for 7 months.. Which is common knowledge to all our family and friends.. this evening, my best friend (who has a 6 month old baby) told me that she is pregnant again.. over dinner in a public restaurant with our other friend at the table who already knew.. She hasn't been trying and didn't even know if she wanted to keep the baby apparently.. please tell me it doesn't make me a horrendous human for feeling like I hate her right now?? of course I'm happy for her but it just hurts.. it hurts that she didn't tell me first when she's my best friend.. it hurts that she told me in a shitty way and it hurts that she's got what I want.. obviously I'll be there and support her but I can't help but feel like I just want to get in my car and drive away from everyone right now.. please tell me this is normal and that I'm not being a horrible friend??
