Low Amniotic fluid

I had my scan on 28 weeks.Dr said everything looks good except the Amniotic fluid is almost 6-5 range, which is low. Mine is First IVF pregnancy, not sure if it matters. They asked me to count on baby movements during quiet hours when I relax and not moving around. 10 kicks in an hour or any movements. I will be undergoing anatomy scan. I had two anatomy scan before but never ever anyone mentioned that I have low amniotic fluid. I am scared and hoping my baby stay stronger and stay with me come on due date. Did anyone of you had similar number, how was your experience? Is your delivery normal delivery? Any inputs would help me. I have done enough research but it scares me more. Thanks all in advance for any input.
