Would it be lazy if...?

So I need to go grocery shopping tonight. The pressure on crotch and legs is unbearable when I have to walk. I want to walk. I know it's good for me and baby. But...I want to stick it out a little longer and would rather not accidentally cause early labor.

I will have just finished an 8 hour day at work as well. Would it be lazy of me if I got one of the chairs/scooters for this particular grocery trip? Lately my husband has been going because he knows how worn out/short of breath I get, but he tends to forget things we need (like toilet paper. Important stuff.) I don't want to deprive someone who needs one though. I'm 37+3 today. Thoughts?
