Low amniotic fluid, anyone dealt with this?

Nikki
So I went in today for an ultrasound. I'm over 11 weeks. Baby looked great with a strong 175 hb, however the amniotic fluid was a little low. Some sonogram pictures it looked okay but others looked small. So Dr said to come back for ultrasound in 2 weeks to make sure fluid looks better. Of course I google and everything I see about low amniotic fluid in first trimester is talking about miscarriage and still birth. So made me a little nervous. I'm a STM and never had this with my son, so I wanted to see if anyone else had dealt with this in a previous pregnancy? Thank you ladies in advance!
