Concerned πŸ˜”

I noticed that I wasn't getting the same symptoms- always hungry & sore breasts. I took a clear blue weeks estimator test & I took one 3 days prior & it said "pregnant 3+" so I knew what to expect. Well the test said "pregnant 2-3", I told my husband & he said it could've been because I've been drinking my decaf teas all night & to take one in the morning, so I just did & it still said "pregnant 2-3" should I be concerned? I'm 6w5d I feel like it should still say 3+ πŸ˜“
