Been taking too much folic?

Hi, I have been taking vitamins - sangobion for iron (I am slightly anaemic), prenatal, and female multivitamins. I am about 5weeks pregnant. I was told today that I shouldn’t have more than 1000mcg of folic acid a day, and my vitamins clearly exceed that limit!! Should I be worried that I’ve been taking too much/excess folic for about 3+ months now? 😰
