Baby competition

So I'm 12w4 days and my sister In law, (my partners sister) is also pregnant; she is 5 days behind me. I'm feeling her family is more excited about her pregnancy than mine, they are all giving her stuff and constantly checking up with her but no one is doing the same for us. My family isn't around much and I've never had a close bond with them, but I am just worried our child will get left out and treated differently 😔 am I being over reactive or what? HORMONES! But it just seems to be how I'm feeling, like she publicly announced her pregnancy on social media and everyone is so happy and can't wait for her baby, we feel uncomfortable even announcing ours. Sorry for whinging, I hope other have similar stories that could relate and help me get over the fear
