Did Amelia Earhart ever get pregnant?

Amelia Earhart, on her last flight, showed evidence (at least to me) of the early stages of being pregnant. On this flight she had morning sickness (supposedly from gas fumes.) She also got weaker with each day passing (like my sister did when she was with child). Amelia also looked a hint larger than she had a few months earlier. So I think that she could have been. But that is not a definite yes.
