I feel so alone and I don’t know what to do

This is mine Nd my husbands second baby his third from another marriage. I feel so alone my husband has not acted exited about ethier one of our baby’s when I suprised him with the tests. Our first we tried for over a year to get pregnant when it finally happened I thought he would be so happy when he opened up the box and pulled the test out he acted pretty indifferent about it. This time we got pregnant after deciding what happens happens and he’s acted like I’m not pregnant at all we went to our anatomy scan last week he stayed with our son because he was napping in the car when I got back I showed him all the pictures expecting him to look and be happy he promptly folded them up and stuck them in the visor when I asked if he was going to look he said I saw. I feel so alone and scared and emotional about it my family and friends haven’t really been around or don’t talk about it. I don’t know if it’s hormonal but I really feel sad and alone and don’t know what to do .
