Thanks for the additional information. It would seem, from both your posts, that there is not in fact any medical way to guarantee that ovulation has not occurred or will not occur around the time of a rape (or any sexual intercourse, for that matter).
Mrs. Tax, this is a pretty good summary of what the CMA believes to be the "Catholic Medical" position in light of the Magisterial teachings of the Church. That is, you are correct: there IS no guarantee.
Deb, "ONLY an RN" is way too humble! God bless all RN's! I understand that we are only about 130,000 short in the US and are importing them from all over the world? I know many RN's and believe they are all a gift from God! My niece is one and she went into Geriatrics. Bless you!
