I freaked

This sounds so stupid.... I had to be tested for anemia today at 33 weeks, and they never informed me that I had to fast for the blood work and they asked if I had eaten or drank anything and I freaked and said I hadn’t. I just dont want to have to come to a doctors office anymore often than i have to. I had a cookie and water will they noticed? 🤦🏼‍♀️
