Hi

I m in my first few weeks of pregnancy and I was thinking if someone could help me .actually I want to buy belly bandit for me to wear after birth but I m very confused what size shall I get at the moment I m wearing size 14-16 and even 16-18 fits me but loose . Shall I wait till the last few weeks of pregnancy or shall I juz buy it now n what size shall I get? Or if you can recommend any good brand

Thank you
