Frustrated at 37 weeks

I’m getting so frustrated because i feel like i can’t get anything done! I try to clean and do housework and start getting sharp pains and have to sit down to breathe. I had plans to go to the grocery store and shop and now I’m afraid to go and just be in pain the whole time. It’s so frustrating. I still have so much to do and all i can do is lay on the couch and eat and sleep!
