Stressing about family visiting during COVID

So it’s been a plan ever since I found out that I was pregnant to have my mom come visit. This was back in December. Last month or two, my mom asked if she could bring my niece. I was on the fence about it but my mom and husband convinced me it would be good to have my 2 year old play with someone while I’ll be busy with the baby. My niece is 7...then my sister asked if she could come for a little too. At first I was excited. But I think I got blindsided by the excitement and QUICKLY regretted it. She bought her ticket so fast. All three of them are coming from the same house but it gives me IMMENSE anxiety not knowing if they’ve been staying out of stores and ect. Three different people going in different places. I’m not sure that I’ll give birth early. But my sister and niece leaves when I’m 39 weeks. If she does come early I hope I miss them while I stay at the hospital and they have to leave. They are flying from Colorado to VA.

My mom and sister fucking had COVID at one point.

I hate myself for not doing what’s best for me, my family and newborn. Now I’m extremely anxious, nervous, and regret everything. If I do have my baby while they are still here...idk what I’m going to do......
