Tips for maintaining an early pregnancy?

Pregnant super early. Any tips for avoiding miscarriage or chemical? I’ve had it happen before. I just know some ladies have great tips or do this don’t do this. I’m not stressing don’t worry and trying to enjoy it but don’t want to do something. Or if there is something I can do I’d like to do that.

I take prenatals, iron, and omega 3 with DHA and all that. Try to get as much sleep as possible. But I’d love any advice thanks!
