vitamin A (retinyl palmitate) & birth defects?

So I'm 6 weeks & a couple days pregnant & I just attted prenatal vitamins on Friday. I'm scared bc the vitamin I got contains 4,000 IU of vitamin A (retinyl palmitate) in each serving. That type of vitamin A has been known to cause birth defects!! Although the risk is low, it's still there! I'm scared I had too much of it! I took 4,000 IU of the vitamin A Saturday night at around 10 or 11 & then that next morning around 11 something, I ate a scrambled egg that contains vitamin A & I ate 3 egg rolls which contain about 5,000 IU of vitamin A bc they have a lot of spinach in them I guess that's why the vitamin A is so high in them & then I ate pizza that had 6% of vitamin A (retinyl palmitate) per serving & I had two servings so it was 12% vitamin A from the pizza! 😩 I'm scared y'all!! I'm hoping I didn't have too much vitamin A bc too much can be toxic ! With the premade vitamin A!
