Condom broke but didn't ejaculate?
The fear that "precum" might get you pregnant IS an irrational fear. It's nothing more that a male's lubrication fluid that he always secretes from the tip of his penis when he's sexually aroused, in anticipation of intercourse. 97% of the time, it doesn't contain sperm cells. You should worry more that the condom might tear, than you should worry about "precum".
That's not irrational. It's a fact - precum can get you pregnant.
Whether or not he ejaculated, pregnancy IS possible. Likely? Probably not. But everyone who is claiming it's impossible is fooling themselves. This is why they sell PlanB.
If a condom tears you do not hear a pop
It's not very likely but not impossible.
No I garentee that you are not pregnant because 1 he did not finish. 2 by the sounds of it you don't track your ovulation. So unless you did it when ovulating and he finished in you, your not pregnant.
