Fun activities to do while pregnant

Probably a silly question but thought I’d ask anyway...

I’m separated from my husband and I don’t have friends like that...

I’m currently in my first trimester, hopefully I feel better soon..

I wanted to ask what are some fun things I can do by myself ? Maybe groups I can join? Is it safe to do stuff like yoga while pregnant ?... just looking at things to get into to keep myself Occupied.. any suggestions ? I work from home so I have a lot of time on my hands..
