Question : Hello, I and my girlfriend were having sex, the condom slip over and maybe, i don't know, happened for a few minutes unproteceted penetration. I don't know because when we noticed it wasn't any fluid of her in my penis and i wasn't ejaculated since i was by far of it. Next, around one hour and half, she tooked the plan B, levanorgestrel, 1.5 mg.

What are the chances of pregnancy? Thanks a lot.

Brief Answer:
The chances of pregnancy are less.

Detailed Answer:
Hi,

Thanks for writing to us about it.

I can understand your concerns.

The chances of pregnancy are very low as she had I- pill within time( with in 72 hrs.).

The chances of pregnancy are low because if I-pill taken within 12 hrs. after unprotected sex it is almost 96% effective in preventing pregnancy.

Hope it is useful, feel free to discuss more.

I understand. Sorry any stubborn, but I presume if I didn't ejaculate (by far as i said) and with the plan-b ingestion, i could say that the possibility are beyond less in normal conditions? Are they even more remotly?

Again, thanks a lot!!!

And what is the window of the collateral effects of the plan-b? She tooked around nine hours early and don't manifest any symptons yet.

Could these collateral efects being confused as symptons of pregnancy?

Brief Answer:
The chances are negligible.

Detailed Answer:
Hello Sir,

I can understand your point.

Yes there are almost negligible chances in your case but nothing is 100%.
I know without ejaculation, there is no chance of pregnancy but precum can also cause pregnancy.
The side effect( collateral effects) of I-pill can mimic the symptoms of pregnancy.
They can occur as early as 2-3 hrs.after taking I-pill and usually resolve in 2-3 days.
It is not necessary that everyone having these symptoms.
You have to wait for her next menses and do not take any stress.
Hope it is helpful, if you need further clarification I feel happy to aid you.
Good luck.
Regards

Brief Answer:
I-pill can cause menstrual irregularities for 2-3 months.

Detailed Answer:
Hello Sir,

Yes, you are right, I-pill can cause menstrual irregularities ( may be her menses occur early or it can be delayed by one week).

But usually these menstrual irregularities may resolve after 2-3 cycle.

That is why if she missed her menses for 7 days than she should go for a home urine pregnancy test to rule out pregnancy.

Yes, little colic is no matter of concern.

Hope it is useful.
