Best friend pregnant

My best friend that I've known for 12 years, we've been besties since the 3rd grade, is pregnant!! She's my sister, my family and a couple of days ago she called me to tell me her big news! I'm over the moon excited for her I moved to new Mexico with my boyfriend last year on Thanksgiving day 2017 so I'm sad I can't be there for her and celebrate with her like we always dreamed of doing. She knows that me and my SO have been trying and she knows that I just had surgery for endometriosis and bilateral cysts but now I'm afraid to tell her if and when I get pregnant. Me and my partner have really been trying this month, BD every other day with no holding back and I feel like this is it. But I'm afraid to tell her if I could be because I want this to be about her as much as I love seeing posts about best friends being pregnant together I feel like she deserves this moment, she's such an amazing person and never had her own spot light or anything she wanted celebrate and I want her to celebrate this. I'm a little upset that she did "not purposely" (I dont like the work accidentally) get pregnant while I had to undergo surgery in hopes to increase my chances but I don't like to feel that way, I know it's just part of ttc and not how I actually feel. But out of all of this, I'm just worried about telling her when I might, there's still that chance i dont get pregnant for a while though, idk I just want to be there for her because I know she needs it now more than ever.. anyone ever go through a situation like this? How'd you get through it? I dont want her to think I got pregnant because she did.. I dont think she will, but pregnancy hormones will probably change her feelings towards things
