Mamas: any advice on when to buy bump support?

Hi everyone,

I'm almost 19 weeks and today during my workout I could feel the tummy/bump (which is all quite low) bopping around and it felt weird, as if I needed some better support for it in order to do jumping etc.

Does anyone have any suggestions as to when I should start supporting my tummy and if so, what kind of support you used?

Thank you!!
