I once worked with a lady who had 2 working sets of reproductive systems.
She had 3 girls (2 years difference between them)... and carried them in different wombs each time... the only noticable difference to her was that her "bump" was either more to the left or more to the right.
Her children were older at the time, so I never saw her pregnant, but she loved telling her right/left bump stories.
Wishing you all the very best for your TTC journey.
