Coffee during pregnancy

I used to drink coffee every morning (recently started to like coffee.. before I got pregnant, used to HATE it). Now I’m realizing I shouldn’t even have coffee since I’m 7 weeks pregnant now. My husband and I go to Dunkin’ Donuts about every weekend or at least once during the weekend. I usually get a medium French vanilla iced coffee.. should I stop? Online it says the caffeine contents are about 238mg.
