Caffeine intake

Hi everyone, this afternoon I had iced lemon tea and 1 cup 12 Oz of latte(quite strong). I'm in week 24 and it's night time I'm having abdominal twinges here and there. Is it my baby is active or is it cause of my caffeine intake? I admit I took abit more then what was recommended. But it's only for today Other days I don't usually take caffeine at all.. please advise I'm worried! #firstbaby #pregnancy #advicepls #pleasehelp
