Do's and dont's pelvic rest

So I was put on pelvic rest yesterday and they didnt really go into details to what I can and cant do. Other then dont insert anything thing into my vagina. But what are other things safe to do or not do?

Like coughing or sneezing

Vacuuming, cleaning??

I know this sounds silly but I'm so afraid I'm going to strain my pelvic and lose my baby again. Anyone have some more info?

I'm a mom of a 7 year old and a 4 year old and they arent the most helpful when it comes to everyday chores lol
