renee... don't be a stupid unrealistic ****... shit happens.. and you have to take care of it however the situation deems necessary. The fact that he actually provided the means, even when he was against it speaks volumes about his character...
And I didn't read the part about after the period when I made my previous reply. There's really no way to get her preggo at the end of her period UNLESS the egg still has not come out (i.e., she's still bleeding). After bleeding stops, the egg is out, and a new one has not yet descended from the fallopian tubes.
You're actually safe for about a week. Why? Because the egg is only descended from the tubes for about 2 days (ovulation) after around the 14th day of her new cycle (2 weeks after the period). If not fertilized, the egg will most likely be re-absorbed into the body. Even then, until the period ends, there is still the chance for fertilization if the egg has not been absorbed into the body, and has yet been removed.
There is also a chance for about a week before this process takes place to get her pregnant. Sperm can live for 5-7 days, so theorhetically, you can bust one in her a week before, some of the little guys can live, and then fertilize the egg when it pops out. It is also (very remotely) possible that one of those little guys can swim all the way up the tubes and nab it.
However, for about a week right after the period, there should be no chance of fertilization. The egg isn't even formed yet, and won't be for 2 weeks.
