As an addendum, OP - why isn't she asking her doctor this?
I get that nobody, especially when you're farther into your childbearing years - wants to be told that they have to wait, or put something so exciting and life changing as having a child on hold... But you're truthfully not doing her any favors as her friend by
1. Telling her time isn't on her side
2. Telling her what she wants to hear
Had to add this.
