Can a woman with a fractured pubic bone still be pregnant?

Yes, but it is recommended to plan for pregnancy after healing.
Pubic bone fractures usually recover to a normal level basically after timely and effective treatment. If pregnancy is carried out before it has healed, the pregnant belly will continue to grow and squeeze the pubic bone as the weeks of pregnancy increase, and if the bony structure of the pubic bone has not recovered at this time, it is likely that recovery will be delayed or another pubic fracture will occur.
