FTM does anyone know?

firt time mommy here

My work recently asked about my OB appointments. They want to know why im having appointments every 2 weeks. And I told them sorry it's my first pregnancy idk whats normal & what's not. Im wondering now because my friends told me they only visited once a month. Not sure what's going on I have an anatomy scan tomorrow & a visit with my ob in 2 weeks

Im only 20 weeks
