Looking for help finding a bra size. 30/38, other sizes mentioned in text.

The calculator on here says I am 32ddd (us). Other calculators have said 30h (us). I recently got on birth control, and have nothing to go by, other than my current 30dd is too small. My measurements are 30.5/29.5/28.5/36.5/38/37 inches. Thanks!
