Help, bubble tea craving

I just drank a cup of Koi hazelnut milk tea with 0% sugar, no pearl no ice. And seems to be addicted and want to drink chicha's dong ding oolong 50% sugar no ice. The last i drink bubble tea i think 1 month ago. Should i wait till my 20 weeks scan then drink chicha? Am scared i drink too often but the craving super strong now lol. Sorry for the silly question.
