Simply but meaningful wedding anniversary ideas?

Backstory: I’m due August 29th with our 3rd baby and our 4th anniversary is August 14th. I feel like I might be having the baby on our anniversary (I had our twins at 30w6d, and I’m currently 33 weeks with baby 3. I never thought I’d make it this far in pregnancy and I’m constantly thinking I could go into labor at any minute due to trauma from the last time around). What are some simple, yet meaningful things I could do/plan for my husband, given that I might not be moving around too much at that point?
