Serious question please don’t judge

I am currently in my 11th week of pregnancy and craving caffeine so bad. I used to be a heavy coffee drinker, as well as caffeinated tea and energy drinks. After falling pregnant I slowed down a lot and had a cup of coffee every now and then until I stopped completely. I drink tea almost every day because that, water, sprite, and orange juice are all I can keep down due to my nausea. I haven’t had coffee in weeks so I went and picked up a frappe from McDonald’s this morning and as soon as I started to drink it I got some mild cramps, I’ve heard coffee isn’t supposed to cause cramps, but the caffeine can be bad for the fetus which is why I cut back heavily… has anyone else drank coffee during pregnancy and everything turned out fine? I feel guilty because I stopped having it for a reason but it’s been so long I didn’t think one would hurt and now I feel like I did something wrong😑

P.s I’m paranoid because this is my second pregnancy, and the furthest that I’ve made it into one since the first time I miscarried at 9.5 weeks
