shapes - How to make two white paths and a white fill transparent over a black image in illustrator?

So I have this tear shape which has a black fill and no outline. I added the following shapes on top of it in sequence:

• 2nd largest circle with black fill and white outline


• 3rd largest circle with black fill and white outline


• Vertical rectangle to create the two semi circles in the 3rd largest circle


• Smallest circle in the middle with no outline and white fill

I been trying to get the white areas to be transparent for many hours. I tried changing the black fills of the circles to transparent fills when combining and subtracting them. I tried separating the circles, I managed to do the small circle transparent in the big tear shape but when I try to do the rest of the bigger circles, I lose the black areas. Then I tried working with the big circle first, the entire tear shape got a white outline.

Any help in me figuring out how to do this will be much appreciated. Thank you.
