Pregnancy

I had a MC in 2017. It was a rough one. My body wouldn’t reject it and it was just rough overall getting back into the swing of things. Me and my husband started trying again as soon as we got the ok. It took us over 1yr to get pregnant with our daughter. I had a pretty easy pregnancy and birth. So why do I get upset/mad when other people announce they are pregnant? It’s even worse when they say “we weren’t even trying”. I have my daughter who is now 7 months who is happy and healthy. So why do I feel that way toward other people when they announce? Am I crazy or just rude?
