Mitigating risk of pregnancy and fluoro

Curious what others are doing. While back did a hip injection under fluoro, patient denied any chance of being pregnant and we routinely record date of last menstrual period. Two days after the injection she has a positive pregnancy test. Her mgy was very low and the risk is minimal, but curious what others do to prevent this from happening. Day of procedure pregnancy test in women of child-bearing age? Avoid fluoro during certain times of cycle? Depend on patient history?
