Burns blister

Ok so basically today I’ve burned my hand and it’s left a big blister full of fluid... now from what I’ve googled it’s a second degree burn which you can treat at home. However I don’t have any of those things so it’s currently wrapped in plaster for tonight so if it pops whilst I sleep it won’t make a mess. Anyways I’m 33 weeks pregnant and worried about infection etc. Does this warrant a visit to the doctors tomorrow or do I just buy stuff to sort it myself? I did read on the NHS website that pregnant women should seek medical attention but it’s not that big and wouldn’t want to waste NHS time or money if it’s nothing serious! Anyway thanks for reading hope someone can help!
