Pray I'm just overreacting 😓😓

I know that I'm not supposed to have little to no caffeine while pregnant but today I decided to treat myself to a mocha cappuccino blast from Baskin Robins (it was SO yummy). A few hours later, I am experiencing mild cramps and bright red bleeding 😩 I have had light bleeding in the previous weeks but nothing like this. I'm 11 weeks pregnant now and I would HATE for something to go wrong just because I wanted to cheat a little. Has this happened to anyone else? Am I maybe stressing for no reason? I pray everything is normal 🤧
