Can You Get Pregnant From Pre-cum 1-3 Days "After" Your Period?

Look. You say 'I'm not sure if I pre-cummed in her.'. This is a silly thing to say. From the time you become aroused, your penis leaks a lubricant. This lubricant is what is called 'pre-cum'. So you most definitely got some in her, since you were not wearing a condom.
I can't stress this enough: EVERY FLUID THAT COMES FROM THE MALE SEX ORGAN CAN (and usually does) CONTAIN SPERM. And yes, this includes urine. ANY FLUID that comes out of the male sex organ while it is in an aroused state DOES have sperm in it. PERIOD.
This being the case, and the fact that the female reproductive organs (all of them) don't care about menstrual cycles (some women have been documented as ovulating [releasing an egg in preperation for fertilization] merely by having an orgasm. So when she menstruates, whether you pull out before or after ejaculation, your wife CAN become pregnant. WILL she? Most likely not, but do you really want to be taking that chance?
USE PROTECTION EVERY TIME. And this don't mean 'if she's on the pill, you're good to go!' As far as I'm concerned, she could have an IUD, be on birth control pills, and be wearing a diaphragm, if you aren't wearing a condom, you're not doing your part.
It's like this: The human reproductive system is DESIGNED to make babies. The pleasurable part is to convince you to let it do what it was DESIGNED to do. The attempted avoidance of reproduction is WHOLLY UNNATURAL and is a product of sentience, and awareness of a modern society, and how having childern will impact our lives. Our bodies don't know a thing about any of that, all they know is that we are supposed to reproduce and pass our genetic code on to the next generations.
So unless you want to pick up the new nickname "Daddy", don't take chances. I've known too many people who thought they were safe with whatever 'protection' they were using... Only to be schooled by their bodies that they assumed wrongly.
Best of luck to you, and I hope I haven't made myself TOO annoying... (^_^)

Chances are, she is not pregnant.  Ovulation normally occurs mid-cycle, and having unsafe sex just 2 days after her period ended, the chances of a pregnancy are very slim.

Yes, I have a friend who got that way and has a boy now.

Yes you can baby!

Actually no you cant. This is the truth. She can only get pregnant from pre-cum if you ejaculated before and didnt urinate after words. Thats the only reason she could become pregnant from pre-cum. See sperm is still in the penis when you ejaculate and by urinating it removes sperm. I dont no where people get it that pre-cum gets you pregnant. But there is a big debate on this subject.

Very unlikely
