Chance of Pregnancy?

[Mando794]

On friday, I ejaculated and and urinated. I urinated again on Saturday 1-2 times again.
Me and my girlfriend had very short anal sex, and she made sure that her underwear was covering her vagina. I personally did not touch the vagina at anytime. But obviously I had pre-*** during anal sex (not protected, and I know it's not the best way to protect yourself from STDs). She then "cleaned" herself and checked and made sure no pre-*** touched her vagina nor her vaginal lips, and there was none to be found. She normally gets her period near the 23rd, and she has went past the all the way till the 1st of the month. Today is the 28th, and no period yet.
So my question: Is there is a possibility that she can be pregnant?

The chances that your girlfriend has got pregnant from this incident is extremely small.

She is not late enough yet. Periods are not like clockwork when sex or stress in involved. 5-6 days late is not late. 12 days is late. You have NO protection from STD this way. Super slim but I've read it's possible to get pregnant but never heard of it happening from the way you described personally. Sounds like the time of the month you did this was more likely around a higher risk for conception but no penetration and covered the area. Risk medium-low. Chance are you can still put pressure on this area of the entrance to the vagina. If really careful very low risk for conception that I know of. Use spermicidal lube.

I am still very worried, but thanks for your input.
I would like to clarify the situation more, so I can get a clearer answer.
Here is the question I put up on Yahoo Answers. (Which their answers are very skeptical):

Ok here is the situation.
My girlfriend's previous periods were the 31st of August and September 1st. She usually gets them near the 23rd of the month, but either way, she got her periods on those dates.
It is now the 2nd of November, and no period. Since the previous latest period was the 1st of September, she should get it in these days right?
I am worried because her and I had had very brief on the 24th of October. I did not touch her vagina, nor the vaginal lips. I did not ***. After she cleaned herself, she found a little bit of blood, but no precum around the area at all. And the last time I ejaculated was the 23rd (a the friday) and I urinated after that, and I did urinated multiple times after. So I am very worried that has not gotten her period.
PLEASE HELP ME OUT HERE! =(

what does urination have to do with it?
take a pregancy test to be sure! but its HIGHLY UNLIKELY!!

If she is Pregnant, it's not from this indecent.

[Mando794]

Well thanks for everyone's input, it really helped me out a lot!

Yesterday, she got her period. RIght on time with the 32 day cycle that cyrstalfresh told me about. So everything is just ok, and I can finally focus on things at home and at school.

Sorry for the double post,
but in regards to the urinating part, I heard that if you urinate after you ejaculate, you "cleanse" out any sperm that is in your penis. Is this is a myth?

[heatherlynn22]

yes it's a myth.

[turkee23]

cleaned out your penis doesnt stop her from getting prego .... if it get inside here then its there and you have a change of pregnancy and STD's

[Birchrus01]

Actually its not a myth. Sperm cant survive the ammonia in urine. Its way we precum. to get all trace amounts of urine out. However, this has nothing to do with getting pregnant. And sperm in the vagina can survive up to 5 days. And for women, peeing doesn't do much, the sperm can hid.

[heatherlynn22]

despite urinating anytime a man engages in sexual activity he release pre ejaculatory fluid. that pre ejaculatory fluid contains sperm, semen contains sperm. you can urinate and urinate there will always be sperm. i remember the night i got pregnant (yes we know which night it was...my hubby was on leave from the marines) and he had urinated and showered...we still managed to get pregnant.
