Have you lost a pet b4?

have you lost a pet before and cried so much? or am i the only crazy one? before my pet went missing, he was so much manja towards me. not he is never close to me. but extra manja with for the last few days maybe because he can sense im pregnant. yesterday, i had my ultrsound and heard my baby's heartbeat. i felt it was the happiest day of life. but today was a total contrast of yesterday. ive been crying so much because i cant stand how sad it is. my husband kept saying to stop crying and stressing because of the baby inside me. but he doesnt understand my grief does he?
