Not Having Fulfilling Support

I'm currently 19 weeks pregnant and struggling to find a support network of new mums. I also don’t have much of a support system from my friends as their main hobby is going to pubs and bars. My partner tries really hard to help but there are some things he just doesn't understand or can’t help with. He also work 60hrs a week whilst I only work 30, so I can be on my own a lot in the house. I also don't live near any of mine or his families.

How do you find local groups of mums to hang out with? I’ve tried asking on Facebook groups and been around my local churches but to no avail. I feel like pregnancy is something I am doing alone right now.
