Is it wrong for me to be jealous

My husband and I were trying to have a baby and it finally happened in February and instead our baby got their wings before we could even say hello. I work in a retail store and deal with hairdressers so we all bc close and we know each other’s families basically but whenever some girls come in here pregnant I get jealous/mad/ and angry that they were able to carry and I couldn’t. I’m beyond happy for them but I know deep down I’m very jealous and we have been trying ever since and sometimes I just want to give up☹️😓
