Dena and Amanda are right. If you question your gender at all, or feel discomfort with your assigned gender role, you are technically transgender.
There are many variations, as Dena also said. I'm not even transitioning, since I'm a nonbinary, partial transmale.
I could qualify for many labels, depending on which definition one prefers.
I am also what some might call asexual, gray demisexual, gender fluid, androgyne, agender, bigender, panromantic, etc., but really that just means that I'm close to the middle of the gender sliding scale, tipped somewhat toward the male side, and without a strong affinity for either side. I suppose the asexual part comes from my gender sides cancelling each other out.
