Jo Wicks has a few on his channel that he did with his wife when she was pregnant
Pregnancy and postpartum TV - great channel on youtube
I also recommend the yoga ball exercises! They are nice, and I also recommend to use a little pillow, some of the women making the exercises arent pregnant and dont realise that being on the floor for a while can start to hurt our butt or knees!

That one is for when you want a bit more effort, makes me feel very strong tbh!

And this channel is typically a bit more relaxing and stretching xx
