A condom did not break, that we know of - but 3 of our four babies were concieved while using condoms. She has taken a test, but it was quite early (1 day late) and so we are waiting until she is 8 days late. We usually have a very active sex life, so DH being out of town - while not completely relevant means that they had far fewer sexual encounters, so you would think it even less likely that she would get pregnant. They had sex twice in the 6 weeks, as opposed to usually 3 times a week.
Dw is scared, and rightly so. She isnt sure what will happen either. Dh is very...dh...he is very calm and "whatever will be will be type mentality..."
