Pregnancy and anti depressants

Ashley • First baby due 2/2/17!!!
Was anyone on an anti depressant when they got pregnant? Me and SO are gonna to TTC soon and I'm on lexapro for severe anxiety. My OB said she may leave me on it if it comes down to it since my anxiety is so severe. Has anyone been on one during the pregnancy? And if so was your baby fine? Second were you able to breast feed?
Thanks ahead ladies❤️❤️
