How do you tell?

Hi, I was wondering if anyone can tell help me. I am obese with loads of belly fat. I am 36 weeks 3 days pregnant. My belly doesn't show at all. I was wondering how do you know if the baby is dropped ?

I know people say take pic compare. I have never taken pics of my belly entire pregnancy. I fit in same clothes before getting pregnant.

If anyone has faced similar situation. I feel lot of pressure now,in my pelvic area was wondering if I have dropped. There is no change in my body from the beginning of pregnancy. I don't show at all. I am total confused state.
