I had sex last friday week and the condom broke but he did not come at all, he peed before the sex ( i heard this would clear the sperm out of his ducts so there would be little or no sperm in his pre *** ) and i was on day 24 of my cycle.I am now 4 days late and I have been stressing about it since it happened and i think that that could be the cause of my late period. What are my chances of being pregnant please help ?
