“Expecting mothers” parking spot

Vi

How soon did y’all start using the “Expecting mothers” parking spot at stores? I’m only 5 weeks and felt a little guilty using it today since I can walk with no problems but at the same time, I was kinda giddy to use it since it’s my first time ever being pregnant. So what do you think? How far along before you can use that spot without guilt? 😂😂 P.S. I know I’m probably overthinking this 😂
