Feeling guilty

I’m 33 weeks today and a couple weeks back my older sister told me she was pregnant. She got pregnant a couple years back and lost it at 15 weeks then she got pregnant again and now he is almost 2. Well she called me today and let me know that she lost this baby at the exact same time as her first and I don’t know what to do. I feel so guilty because I have been complaining this entire pregnancy about being miserable but at least I didn’t go through a loss. I just don’t even know what to say to her.
