B Did intercourse take place on a hard or soft surface?
What I remember of them: No orgasm for me, put in a clean diaphragm immediately afterwards, I knew the morning after conception, 1st pregnancy ended in missed abortion followed by D&C at 11 weeks post-gestation, cause known & not medical; 2nd ended in live ceasarian delivery at 10 months, 2 weeks post-gestation. The most significant factor in my unscientific opinion was that he had no, and I only one, previous sexual partner. I did stop my prescription meds dead (with permission) before conception.
