Hello and thankyou for approaching DoctorSpring with your query.
I have gone through your case and understand your concern.

Your chances of getting pregnant are nearly zero. Let me explain why.
1) You were on your 5th day of your period. Assuming you have a 28 day cycle, the 5th day of your period is during the 'safe' period of your cycle (unless your periods come earlier than 28 days)
2) Your boyfriend was inside only for 10 secs and did not ejaculate, hence semen would not have entered your uterus. It is possible that sperm may be present in the precum but chances of this causing pregnancy is highly unlikely.
3) You took the plan B 12 hours later. If plan B is taken within 24 hours it is 95% effective.

With the above 3 combinations, your chances of getting pregnant are close to or nearly zero.

I hope this has helped.
Thankyou

What i do not get is that i got another period 2 days after my period ended, is it something i should be worried about? when will i get my next period?



Hello, Please can you tell me the following so I can give you an informed opinion. 1) When was your last period? And when did did your period repeat?2) When did you take plan B?3) Usually how long is your menstrual cycle (Ater how many do you get your next period)?What you experience is probably due to menstrual irregularities that is caused by plan B as a side effect, if this episode occurred after taking plan B. Please reply and I will advise you accordingly. Thankyou.

EDITED:
Hello. I just saw your edited question. If you got your period again after plan B earlier than your expected date it is because of the menstrual irregularities due to hormonal changes caused by the plan B pill and is nothing to worry.

Plan B pill is relatively safe. But it does cause a few side effects like menstrual irregularities, spotting, nausea, vomiting, abdominal pain, fatigue, headache, dizziness and breast tenderness.

I cannot say for sure when your next period will be as your cycle will be a bit irregular due to the plan B.
However since you have already had your period after the last episode with your boyfriend there is no chance that you will be pregnant.

I hope this has helped.
Thankyou
