Preventing Labor?

Ladies I’m 38 weeks today, currently have Covid and just miserable (I feel like I pulled a lower belly muscle, can’t sleep, consistent headache, a cough that’s causing me to throw up, and my twin boys that are almost 3 1/2 are both sick so their schedule is messed up). My OB canceled my apt for this week and said he would see me at my next apt so we can talk about delivery, at that apt I will be out of the 10 day quarantine. I would prefer to wait until the 28th (my scheduled csection date), so we can make sure the virus isn’t active in our house and I can have the house sterilized a few times before my LO comes home. So basically, do you have any tips to prevent labor before the 28th?
