How do you make friends being a sahm

I’m an eighteen year old stay at home mom with no friends beside my husband😥. By no friends I mean no friends, the only people I talk to is a couple of family members and my husband and my daughters doctors since she was born premature. I feel like it shouldn’t be hard to make friends but every Highschool friend I had turned their back on me when I got pregnant, and with me having no job I can’t just go to work and make work friends either. I just want to talk to somebody and go out with somebody and just have a good time instead of staying cooped up in the house. My husband has friends and goes out atleast twice a week and I know it’s wrong to be spiteful but it makes me upset because all of his friends smoke and wouldn’t bother to hold off if I was to come and bring the baby and hang out a couple of times. I don’t see why it would be hard I’m 18 yeah I’m a mom but I love being a mom at 18 and I wouldn’t trade it for anything, and I’m a sweat pants and baggy shirt kinda girl at home and I dress up nice whenever I go out, I’m into excercising and being healthy and all but I for the life of me can not find any friends to go out with or even just to talk to🤔😣
