Lexapro while pregnant

I am currently taking 20mg of Lexapro and am about 5-6 weeks pregnant. Still waiting to be seen by my FNP. Previously she had mentioned that I could stay on it even though they are possible side effects in the 3rd trimester and birth. I don’t feel comfortable continuing to take because of that. I will wait to stop until I talk to her of course. I am just wondering if anyone had success switching to another anti-depressant during pregnancy? If so, which one? Thanks!
