New diva cup after pregnancy

Diva cup makes different size models for before and after having a baby.

Did anyone who used a diva cup before pregnancy NOT get the next size up?

Some women have said they continued to use their pre-pregnancy cup after birth with no issues.

I had the original size 1 before diva cup changed their models from 2 different sizes to 3 different sizes, and when I became pregnant, I threw my cup away assuming I was going to buy the after-baby cup size. But I actually have a spare original size 1 and I don’t want to buy another new cup if I don’t have to.
