My best friends pregnant

So I've been debating whether or not I wanted to post this because it's a vent. My best friend texted me yesterday and told me she just found out she was pregnant. I literally started crying of course I'm so happy for her but she wasn't even trying to have a baby and my boyfriend and I have been trying for months. She's the only one that knows we've been unsuccessfully trying to have a baby and of course being my best friend she tells me everything that she's feeling and her fears and she told me before she told her husband and now I keep getting videos and pictures of her telling him and I'm trying so hard to be supportive but it's so hard and I'm kind of mad that she's not being more sensitive to the fact that I've struggled. Idk I just feel like it's so unfair and I don't know what to do or feel at this point.
