I appreciate your query.
Even with brief penetration, if the condom was not properly worn , or it got torn, that is, if there is a possibility that seminal fluid entered the vagina - then technically there is a chance of pregnancy
This is particularly so, if it occurred around mid menstrual phase - around time of ovulation.
Also, about the Unwanted - 72, following are the statistics for emergency contraceptive
95% effective if taken within 24 hours of intercourse, 85% if taken within 25-48 hours; 58% if taken after 49 but before 72 hours. If used mid-menstrual cycle, one in every 20 women is likely to conceive.
So, right now, you have a fairly good chance of being protected.
However, if she misses her period, perform a home ( HCG
) urine pregnancy test within a few days after the missed period.
You can definitely go for medical abortion
if you detect the pregnancy early.
However, please do not panic for now, as you took the pills in time, and also be careful with protection in future
